texture::Texture,
(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

handle::Sampler,
(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

/// A handle to a greedy meshed color-light texture as a resource.
(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

pub fn new(
(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

sampler,
(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

) -> Result<(), RenderError> {
(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

/// Create a new texture from the provided image.
(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

/// Queue the rendering of the provided UI element in the upcoming frame.
(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

&mut self,
(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

/// Create a new pipeline from the provided vertex shader and fragment shader.
(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)

(See sharp/lod-history) LOD, shadows, greedy meshing, new lighting, perf --- Pretty much a Veloren fork at this point. Here's a high level overview of the changes (will be added to CHANGELOG just before merge). At a high level this MR incorporates roughly two groups of changes. The first group consists of new game features: more flexible map sizes, level of detail terrain, shadow maps, and a new lighting engine. This is "feature work" that (mostly) only adds new things to Veloren, and mostly shouldn't affect old stuff. The second big group of changes are those addressing the fallout from all the new features. These include performance fixes of various sorts: the addition of multiple graphics options and optimization of the cheap ones to avoid work, switching all voxel models to use some variant of greedy meshing, switching over much of our CPU-side vector math to exploit SIMD instructions (coinciding with a fork of `vek`), and a rewrite of how the UI handles text rendering (coinciding with updates to our fork of `conrod`). Making Veloren's hardcoded colors appear correct under the new lighting engine also required considerably changes (TODO: Fill in this section when it's complete). The second category of changes often heavily touches code owned by other people, including frequently modified code "owned" by a handful of people, so I recommend that this code be reviewed particularly carefully. --- At a high level (each will be described in more detail below): - The world map has been refactored. - The world size is no longer hardcoded (@zesterer). - The map generation code was made generic to allow using it outside of the `world` crate (@zesterer). - On world creation, we now compute *horizon maps* (@zesterer). - The way we pass the world from the server to the client has been updated (@xMAC94x). - Artifacts related to image rotation were fixed (@imbris). - Multiflow rivers were enabled (@zesterer). - In the process of making changes related to the world map, various incidental fixes and optimizations were required. - The new *level of detail* feature was added (@zesterer wrote part of this and has checked out the rest). - A new LOD terrain rendering step was added to the pipeline. - The LOD terrain quality was made configurable via a graphics setting. - Horizon maps were used to cast shadows from LOD chunks on both LOD and non-LOD terrain. - A "voxelization" effect was incorporated into rendered LOD terrain to make it blend better into the world. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Veloren's lighting has been completely overhauled (@zesterer has already checked most of this out). - A semi-accurate index of refraction was assigned to our materials. - A new, more realistic, physically based approach to lighting was used using the *Ashikhmin Shirley* BRDF. - We emulate *atmospheric scattering* using equations designed for measuring solar panel light exposure. - We attempt to compute *realistic light attenuation* in water using its real material properties. - In the process of making changes related to LOD, various incidental fixes and optimizations were required. - Point and directional lights now cast realistic shadows, using *shadow mapping.* (@imbris, @zesterer, @Treeco, @YuriMomo) - Point light shadow maps were added to the rendering pipeline, using geometry shaders and *seamless cube maps*. - Directional light shadows were added to the rendering pipeline, using LISPSM together with disabling *depth clamping*. - "Shadow-only" chunks and NPCs were added to prevent shadows from models behind you from disappearing. - In the process of making changes related to shadow maps, various incidental fixes and optimizations were required. The addition of shadow maps, LOD terrain, and the new lighting all led to significant performance degradation, on top of other changes happening in master. Therefore, a large number of performance improvements were also needed: - The graphics options were made much more flexible and configurable, and shaders were optimize. - New options were provided for how to render lights and shadows (@Pfauenauge, @zesterer). - Graphic setting storage and configuration were overhauled to make adding new features easier (@Pfauenauge, @imbris). - Shaders were rewritten to utilize GLSL's preprocessor to avoid overhead (@zesterer, @YuriMomo). - In the process of making changes related to providing additional rendering options, various incidental fixes and optimizations were required. - Voxel model creation was switched to use *greedy meshing.* - A new voxel meshing method, greedy meshing, was added (@imbris). - Uses of the older meshing methods were migrated to use greedy meshing (@imbris, @jshipsey, @Pfauenauge). - New restrictions were added to terrain, figure, and sprites to future proof them for further optimizations (@jshipsey, @Pfauenauge, @zesterer). - Most positions are now relative to either chunk or player position for better precision (@imbris, @zesterer, @scottc). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - Animation and terrain math were switched to use SIMD where possible. - Fixes were made to vek to make its SIMD feature usable for us (@zesterer, @imbris). - The interface and types used in bone animation were changed in various ways (@jshipsey, @Snowram, @Pfauenauge). - Redundant code generation for body animation is now partly taken care of by a macro (@jshipsey, @Snowram, @Pfauenauge). - Animation code was modified to to use vek's SIMD representation where possible (@jshipsey, @Snowram, @Pfauenauge). - Terrain meshing code and shadow map math were also modified to use vek's SIMD representation (@imbris). - SIMD instruction generation was enabled (@YuriMomo, @jshipsey, @Snowram, @imbris, @Angelonfira, @xMAC94x). - In the process of making changes related to greedy meshing, various incidental fixes and optimizations were required. - The way we cache glyphs was completely refactored, fixed, and optimized. - Our fork of `conrod` was optimized in various ways (@imbris). - Our fork of `conrod` now exposes whether a widget was updated during the current frame (@imbris). - Our use of the glyph cache was rewritten for correctness (@imbris). - A *text cache* was introduced that lets us skip remeshing glyphs that have not changed (@imbris). - Various changes were made to reduce pressure on the glyph cache, with more planned (@imbris, @Pfauenauge). - In the process of making changes related to the glyph cache, various incidental fixes and optimizations were required. - Colors were changed to keep Veloren's look consistent with master. - Some older tree models were brought back (@Pfauenauge). - TODO(@Sharp): All hardcoded colors were extracted and made hotloadable. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Hardcoded colors were fixed to conform to Veloren's style. - TODO(@Treeco, @Pfauenauge, @imbris, @jshipsey): Color models were fixed to conform to Veloren's style. A detailed description of the involved changes follows. --- - The world size is no longer hardcoded. All functions dependent on world size now take a `WorldSizeLg`, which holds the base 2 logarithm of each actual world dimension and is guaranteed to maintain certain properties (outlined in `common/src/terrain/map.rs`). Additionally, many utility functions that utilize the world size were moved into `common` as well (mostly `common/src/terrain/mod.rs`). Finally, the world map format was updated in order to store its size explicitly, with a migration path from the old format that should work whenever the old formatted map was a square (practically always). See `world/src/sim/mod.rs` for these changes. - The map generation code was made generic to allow using it outside of the `world` crate. The parts of the map generating code that do not need to query the world were moved over to `common/src/terrain/map.rs`, allowing them to be used from the client without creating a dependency on `world`. The rest of it was turned into helper functions in `world/src/sim/map.rs`, which can be passed as closures to the generic map generation code to complete its construction. This also means that colors are now passed in separately to the map generation function. See <https://veloren.net/devblog-78/> for more details. - On world creation, we now compute *horizon maps*. See the function in `world/src/sim/util.rs`. Given a height map and a plane intersecting that height map, our horizon maps allow us to encode enough information to reconstruct shadows for each point on the height map using only the *horizon angle* (the angle at which the sun starts to become visible). As Veloren's sun only covers one plane, this is sufficient for encoding sun shadows for LOD terrain, by encoding two angles per chunk (one for each 90 degrees the sun covers). We can also use this for the moon, if we want, since the moon follows the same path. Additionally, we store the *height* of the furthest occluder, to try to make the shadows volumetric; so this means 4 bytes in total for each chunk. Support for horizon maps has been merged into the map functionality in common as well. - The way we pass the world from the server to the client has been updated. Rather than passing the prerendered map, we instead pass three maps with values for each chunk; one with the color information, a second with altitude information, and a third with horizon map information. We then reconstruct the map on the client, together with some additional information we send from the server (like the sea level and maximum height). See `common/src/msg/server.rs` for a detailed description of the format of `WorldMapMsg`, and `server/src/libr.rs` and `client/src/lib.rs` for details of the map construction and parsing. - Artifacts related to image rotation were fixed. See the commit message for commit SHA `cf74d55f2e3d2ae7d25fd68d5c73b01a6afde86e` for a detailed explanation. This involved changes to shaders, the addition of a new type of graphic (also reflected in the graphic cache) that allows specifying a border color (which automatically makes the associated texture immutable), and some related fixes. I reproduce the first two paragraphs of the MR description as well: ``` Fix map image artifacts and remove unneeded allocations. Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). ``` - Multiflow rivers were enabled. This does not really need to be part of this MR, and would be easy to revert, but since it seemed to provide a nice improvement it's currently packaged with it. We already computed multiple outflows from each chunk for erosion purposes long before this MR. However, we never modified river rendering to be able to handle this case (just a single downhill river flow is complex enough!) so this was not exposed when deciding which chunks were rivers. Now that - In the process of making changes related to the world map, various incidental fixes and optimizations were required. Some examples of fixes include making sure terrain is never lowered to below sea level (to make the shadow maps report correct values), fixing map altitudes and colors to understand things like cliffs and "block level" coloring (that doesn'te xist on the column level), and fixing a crashbug when rendering images for the UI where source pixels are strongly rectangular. Some examples of related performance fixes include avoiding allocating a fresh vector for all the maps (i.e. copying it over to change the format from `[u32; n]` to `DynamicImage` and then copying again to convert to `RgbaImage`), and instead using the `gfx::memory::slice` function to accomplish the same thing. These sorts of changes are spread all arond the code. This includes the additon of a new scene, `voxygen/src/scene/lod.rs`, a new pipeline `voxygen/src/render/pipeline/lod_terrain.rs`, and new shaders `assets/vxygen/shaders/lod-terrain-vert.glsl` and `assets/vxygen/shaders/lod-terrain-frag.glsl`, as well as associated changes to the renderer in `voxygen/src/render/renderer.rs`. The main idea behind our initial approach to LOD was to take the world data we now get from the server (altitude, color, and horizon mapping). - Some previously computed values were turned into shader uniforms for better prediction on weak processors. (@zesterer) - Calls to power or trig functions were removed or replaced with multiplications, where possible. - After some deliberation - To properly handle sprite "waving" for nearby sprites, We explicitly designed the greedy meshing system with figures and sprites in mind. In both cases, we want to be able to *efficiently* pack many different models into the same texture, especially in cases where we know we will either not be removing any of the grouped-together from the models from the texture, or will remove all of them at once (so they can be packed into some specific subtexture). For sprites, since we know every model in advance and never intend to deallocate them, we currently pack them all as efficiently as possible into one giant tetxure atlas. However, in the future we might opt to pack them slightly less efficiently in exchange for shrinking the sprite vertex size. For figures, we pack all the textures for each *model* into the same atlas. is a global texture atlas used for every sprite, and for figures which is why we have the ability to mesh multiple models to the same texture area (using the simple texture atlas allocator) without requiring intermediate vector allocations. This is accomplished by delaying the time when we actually write the color and light data to the texture until *after* all the model vertices have been meshed; then, we can just allocate the whole color/light array at once, making the atlas we use an exact fit. In computer science-y terms, we accomplish this delay by, after we perform the initial greedy meshing (without texture information), not continuing to create the texture data, but instead constructing a *continuation*--that is, a function that, when called, will execute the rest of the computation. We push this continuation (which in Rust terms is a `FnOnce` closure that takes the `ColLightsInfo` that it is supposed to write to as context) onto a onto a vector resizing. To allow for suspended writes to texture data, Rust pointed out to me that the continuation that would eventually write the color and light data to the texture atlas (the one that is shared by all models sharing the same greedy mesher) would have to *own* whatever data it mshed. Because we often generate the model data to mesh as a temporary in `voxygen/src/load.rs`, the - Matrix multiplications in the shader were reduced for figure data (@zesterer). - Vertex "waves" for fluid data were removed. - Terrain "bending" near edges was removed. - Scaling was fixed to make sure empty space was not introduced in a space previously occupied by a block. It was also changed to take ownership of its voxel data, rather than sharing it, to let it be used with meshing. - Rust's nightly version was bumped in order to use the `array_map` function, which lets us reuse more code between the simple map and `FigureModelCache`. - PositionedGlyph::standalone. --- I tried to cite sources in many cases[^realtime],[^lloyd],[^lispsm],[^pbrt],[^greedy],[^tjunctions] where I needed features from elsewhere but I am particularly grateful for the following resources, esepcially where they have accompanying source code.

Specifically, we address three concerns (the image stretching during rotation, artifacts around the image due to clamping to the nearest border color when the image is drawn to a larger space than the image itself takes up, and potential artifacts around a rotated image which accidentally ended up in an atlas and didn't have enough extra space to guarantee the rotation would work). The first concern was addressed by fixing the dimensions of the map images drawn from the UI (so that we always use a square source rectangle, rather than a rectangular one according to the dimensions of the map). We also fixed the way rotation was done in the fragment shader for north-facing sources to make it properly handle aspect ratio (this was already done for north-facing targets). Together, these fix rendering issues peculiar to rectangular maps. The second and third concerns were jointly addressed by adding an optional border color to every 2D image drawn by the UI. This turns out not to waste extra space even though we hold a full f32 color (to avoid an extra dependency on gfx's PackedColor), since voxel images already take up more space than Optiion<[f32; 4]> requires. This is then implemented automatically using the "border color" wrapping method in the attached sampler. Since this is implemented in graphics hardware, it only works (at least naively) if the actual image bounds match the texture bounds. Therefore, we altered the way the graphics cache stores images with a border color to guarantee that they are always in their own texture, whose size exactly matches their extent. Since the easiest currently exposed way to set a border color is to do so for an immutable texture, we went a bit further and added a new "immutable" texture storage type used for these cases; currently, it is always and automatically used only when there is a specified border color, but in theory there's no reason we couldn't provide immutable-only images that use the default wrapping mdoe (though clamp to border is admittedly not a great default). To fix the maps case specifically, we set the border color to a translucent version of the ocean border color. This may need tweaking going forward, which shouldn't be hard. As part of this process, we had to modify graphics replacement to make sure immutable images are *removed* when invalidated, rather than just having a validity flag unset (this is normally done by the UI to try to reuse allocations in place if images are updated in benign ways, since the texture atlases used for Ui do not support deallocation; currently this is only used for item images, so there should be no overlap with immutable image replacement, so this was purely precautionary). Since we were already touching the relevant code, we also updated the image dependency to a newer version that provides more ways to avoid allocations, and made a few other changes that should hopefully eliminate redundant most of the intermediate buffer allocations we were performing for what should be zero-cost conversions. This may slightly improve performance in some cases. commit ad18ce939940a8c697270f6e9b94db9942fd8295 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 13:21:09 2020 +0200 Fix continent scale hack. commit 36b1cb074f5b195aebd7dbbc3da7f0246a1a18ec Author: Joshua Yanovski <pythonesque@gmail.com> Date: Tue Jul 28 12:11:40 2020 +0200 Enable loading different sized maps without a recompile.

Erased almost every instance of WORLD_SIZE and replaced it with a local power of two, map_size_lg (which respects certain invariants; see common/src/terrain/map.rs for more details about MapSizeLg). This also means we can avoid a dependency on the world crate from client, as desired. Now that the rest of the code is not expecting a fixed WORLD_SIZE, the next step is to arrange for maps to store their world size, and to use that world size as a basis prior to loading the map (as well, probably, as prior to configuring some of the noise functions). commit 30b1d2c6428230a9eaa0d749cdcbbd6f1cbccd78 Merge: 7d56ba31b 1377b369f Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:58 2020 +0200 Merge remote-tracking branch 'origin/sharp/small-fixes' into sharp/small-fixes commit 7d56ba31b445441461b28a07fc495d7d4f047c17 Merge: 2101113b4 598f14b25 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Mon Jul 27 13:16:27 2020 +0200 Merge remote-tracking branch 'origin/master' into sharp/small-fixes commit 1377b369f6db2258e910d467a5740f31789e3ded Author: Monty Marz <m.marzouq@gmx.de> Date: Sun Jul 19 23:25:38 2020 +0200 more saturated pumpkins commit ae8d50527f93bb0616c2ad46ce4dacb63bc37c6d Author: Monty Marz <m.marzouq@gmx.de> Date: Sat Jul 18 20:29:56 2020 +0200 acacia models commit 2101113b467e691de787392d7f20f1745f5637bd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sat Jul 18 18:55:25 2020 +0200 Higher detail LOD. commit add2cfae04b4385fa5590e11e2bd5229d9dee0aa Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Jul 16 01:57:39 2020 +0200 Revert some irrelevant stuff. commit 2e2ab3dc1eaa59a4aef7f8d34a53d8aae4c8553a Author: Joshua Yanovski <pythonesque@gmail.com> Date: Wed Jul 15 13:30:49 2020 +0200 Fixing various things about shadows. * Correcting optimal LISPSM parameter. * Figure shadows are cast when they're not visible. * Chunk shadows stay cast until you look away. * Seamless cubemaps for point lights. * Etc. commit 6c31e6b56217274285b597af297036691ea5d897 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 19:50:26 2020 +0200 Fix shadow creation. commit 6332cbe006115ae205597529cd8bbccd146c2cca Merge: be438657c 930e0028b Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:47:00 2020 +0200 Merge branch 'master' of gitlab.com:veloren/veloren into sharp/small-fixes commit be438657c33d7b5bfb0a9582c3ed3fd366637323 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Sun Jul 12 18:28:08 2020 +0200 Tweaks to shadows.

Making maps brighter. This is probably not the right way to do it, but oh well! commit 32b2c99109dd486aa922886081068f9c550c83f2 Author: Joshua Yanovski <pythonesque@gmail.com> Date: Thu Apr 2 02:46:36 2020 +0200 Horizon mapping and "layered" map generation. Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD. commit f8926a5737ddc51f3d585c651a64c43677aae0f4 Merge: a1aee931e 875ae6ced Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Mar 13 13:32:42 2020 +0100 Merge remote-tracking branch 'origin/master' into sharp/map-colors commit 4c65a5aed353b119aea65a2aaeb94549b67beb42 Author: Treeco <5021038-Treeco@users.noreply.gitlab.com> Date: Mon Feb 24 16:48:05 2020 +0000 Made LOD setting slider exponential commit 2fa7b2d20d7233dc8bfd64f9f7f54617575248f1 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 17:49:53 2020 +0000 Added mist to LoD commit aab059a450b5f635777129ff82cc15b662965c3c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 15:14:06 2020 +0000 Added LoD slider commit 779c36b538121c5ade3633ae5cb67bb14c8c3877 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:54:55 2020 +0000 Reduced cost of vertex pushing commit 9fea150473906b166365b738ebcea07c697daf3d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 12:38:53 2020 +0000 Fixed maths, improved LoD resolution commit 5481df38fea5bf183ff376a3337179cfaa5233dc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Feb 24 11:22:50 2020 +0000 Dynamically relocate LoD vertices to enhance details commit a3e36a50ababd615da7db1b26158c7906a5def01 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 18:13:51 2020 +0000 Simpler terrain spiral rendering commit 255f450ae9ac8763db4bede075fb409161ed57cc Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:53:17 2020 +0000 Better LoD precision commit 3d027aebe812a5b8658a4eb8123dc9f61b3776d2 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 16:04:03 2020 +0000 Better falloff commit be775c9484b457b2c0b1a494aec03392d0c70e76 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Feb 23 15:30:45 2020 +0000 Applied good ideas from experimental branch commit 58587b68545a23c5c04ab4574a4b94b3bc982246 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 16:15:13 2020 +0000 Minor fixes to LoD merging commit 7b42aebd709c14df2db766aad61d9280ad24d84d Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 15:04:44 2020 +0000 Capped LoD dragging commit 8aafc559f87124e1ea5ca6e3ddc2aa0c242d793c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:54:37 2020 +0000 Better blending between LoD and terrain border commit edd3455d5161792d87ddc8eadc0ecbad5532b284 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:40:19 2020 +0000 Fixed LoD z depth, added sea level offset commit b9b06744620114dd5556e73f64fa93c145503a7c Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 14:27:43 2020 +0000 Better LoD smoothing commit a1aee931e790431560cd2d953ad61d9497072afd Author: Joshua Yanovski <pythonesque@gmail.com> Date: Fri Feb 21 14:52:17 2020 +0100 Adding shadows. commit 2400786c13dd891c131ed86d48d05df516a8a778 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Feb 21 13:48:40 2020 +0000 Use world map as LoD source commit dbf650f504a4c25fbbc2096ac3616c736bf52d23 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Mon Jan 20 00:48:14 2020 +0000 Better clouds at distance commit 5e6f81b86cdb9730b9b056877b19257075fd5fa8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Sun Jan 19 23:59:02 2020 +0000 sync commit 745e7540ddb000cc645f612767b337c2ddc3f7c0 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 12:40:48 2019 +0000 Improved cloud falloff mist, faster noise sampling commit f6a200d0cb866196ba57697466755f9e0c7ea5d8 Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Fri Nov 22 10:09:00 2019 +0000 Improved long-range depth precision, removed unnecessary LoD polygons commit 63d1b2bb2292898d59fb4f4e502201103dfeb86f Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 20:57:46 2019 +0000 Working LoD shader commit f13d98ee3e58f881e8b978861a67663b59ed91ec Author: Joshua Barretto <joshua.s.barretto@gmail.com> Date: Thu Nov 21 11:03:40 2019 +0000 LoD first attempt (stack overflow issue)
