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.

Currently, this just entails humanoid colors. There are only three
colors not handled; the light emitter colors in
common/src/comp/inventory/item/tool.rs. These don't seem important
enough to me to warrant making hotloadable, at least not right now, but
if it's needed later we can always add them to the file.

commit cf74d55f2e
Author: Joshua Yanovski <pythonesque@gmail.com>
Date: Wed Jul 29 18:29:52 2020 +0200
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).
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 13b6d4d534
Author: Joshua Yanovski <pythonesque@gmail.com>
Date: Tue Jul 28 10:55:48 2020 +0200
Removing WORLD_SIZE, part 1.
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 32b2c99109
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.

LoD first attempt (stack overflow issue)
increase the slowlorris timeout. for some reason it seems to trigger alot more often since commit: `75c1d440` but i have no idea why.
My guess would be that the initial sync now sends way more data which slows down TCP to be > 10ms and trigger. Note: the fix might cause small lags when slow people try to connect to the server
We MUST handle them and we are not allowed to act on a stream after it failed, as i am to lazy to change the structure to ensure the client to be imeadiatly dropped i added a AtomicBool to it.
- make it harder for the server to crash and also kill invalid sessions properly (instead of waiting for them to close)
- introduce macros to reduce code duplication
- added tests to check for valid handshake as well as garbage tcp
- voxygen abort when the server has a invalid veloren_network handshake, e.g. by outdated version instead of try again
- rename Network `Address` to `ProtocolAddr` as sugested by zest as it's a combination of Protocol and std::io::Addr
- remove the manual byte arrays in `protocols.rs` with something more nice
- API behavior switched!
- the `Network` no longer holds a copy of participant, thus if the return of `connect` (before `Arc<Participant>, now `Participant`) got dropped, the `Participant::Drop` is triggered!
- you can close a Participant async via `Particiant::disconnect()`, no more need to know the network at this point
- the `Network::Drop` will check and drop not yet disconnected Participants.
- you can compare Participants via PartialEq, if they are true they point to the same endpoint (it checks remote_pid)
- Note: multiple Participants are only supported in theory, wont work yet
Additionally:
- fix some `debug!`
- veloren-client will now drop the participant gracefully on shutdown
- rename `error` to `debug` when 2 times Bparticipant shutdown is called, as it is to be expected in a async runtime
- replace serde_derive by feature of serde
incl. source code modifications to compile
- reduce futures-timer to "2.0" to be same as async_std
- update notify
- removed mio, bincode and lz4 compress in common as networking is now in own crate
btw there is a better lz4 compress crate, which is newer than 2017
- update prometheus to 0.9
- can't update uvth yet due to usues
- hashbrown to 7.2 to only need a single version
- libsqlite3 update
- image didn't change as there is a problem with `image 0.23`
- switch old directories with newer directories-next
- no num upgrade as we still depend on num 0.2 anyways
- rodio and cpal upgrade
- const-tewaker update
- dispatch (untested) update
- git2 update
- iterations update
- mostly its the message handling put now in a async wrapper
- add some fixes to pass without warnings and make clippy happy
- some network error handling is ignored, this can be improved but is no blocker
this is the part which prob has less Merge conflics and is easy to rebase
the next commit will have prob alot of merge conflics
followed by a fmt commit
* Added chat message when an item is picked up
* Changed InventoryUpdateEvent::Collected to InventoryUpdateEvent::Collected(Item) to facilitate the client being aware of what was picked up
* Added SfxInventoryEvent enum to allow different sounds to be used based on the item type. The RON mapping/de-serialization doesn't support matching on structs so we have to give it fixed enum values which are determined in TryFrom<&InventoryUpdateEvent> for SfxEvent
* Refactored InventoryManip::Pickup arm of match in inventory_manip::handle_inventory for clarity/better warning messages
* Fixed a bug that prevented the CollectFailed event from being raised when a player's inventory is full
* Added a panic for the situation where an item is pushed into the players inventory and then the deletion of the entity fails as this would indicate an item dupe bug - this could potentially be reworked to pull the item back from the player's inventory but this seems like there's be a more correct transactional way to do this.
* Added two temporary sounds to prove the per-item sound functionality (pickup sounds for Swords and Staffs)
- Handle/notify the client of errors during character load by returning to character select with the error, clean up client and server states
- Add player_uuid check when loading character data.
- Completely removed both `log` and `pretty_env_logger` and replaced
with `tracing` and `tracing_subscriber` where necessary.
- Converted all `log::info!(...)` et al. statements to just use the
shorthand macro i.e. `info!`. This was mostly to make renaming easier.
- authc no longer uses reqwest
- image only supports PNG
- replace routille with tiny_http
- several other dependencies
- cargo upgrade
- following improvement was measured on R7 1700X:
before:
- cargo build: 3076.73s user / 4:45 total / 589 dependencies
- cargo test: 6118.38s user / 7:30 total / 959 dependencies
after:
- cargo build: 2680.54s user / 4:05 total / 480 dependencies
- cargo test: 5351.81s user / 7:04 total / 791 dependencies
- added xMAC94x to CODEOWNERS for Cargo.toml, he will protect them from now on and hit people with evil looks ;)
- this bug was initially called imbris bug, as it happened on his runners and i couldn't reproduce it locally at fist :)
- When in a Handshake a seperate mpsc::Channel was created for (Cid, Frame) transport
however the protocol could already catch non handshake data any more and push in into this
mpsc::Channel.
Then this channel got dropped and a fresh one was created for the network::Channel.
These droped Frames are ofc a BUG!
I tried multiple things to solve this:
- dont create a new mpsc::Channel, but instead bind it to the Protocol itself and always use 1.
This would work theoretically, but in bParticipant side we are using 1 mpsc::Channel<(Cid, Frame)>
to handle ALL the network::channel.
If now ever Protocol would have it's own, and with that every network::Channel had it's own it would no longer work out
Bad Idea...
- using the first method but creating the mpsc::Channel inside the scheduler instead protocol neither works, as the
scheduler doesnt know the remote_pid yet
- i dont want a hack to say the protocol only listen to 2 messages and then stop no matter what
So i switched over to the simply method now:
- Do everything like before with 2 mpsc::Channels
- after the handshake. close the receiver and listen for all remaining (cid, frame) combinations
- when starting the channel, reapply them to the new sender/listener combination
- added tracing
- switched Protocol RwLock to Mutex, as it's only ever 1
- Additionally changed the layout and introduces the c2w_frame_s and w2s_cid_frame_s name schema
- Fixed a bug in scheduler which WOULD cause a DEADLOCK if handshake would fail
- fixd a but in api_send_send_main, i need to store the stream_p otherwise it's immeadiatly closed and a stream_a.send() isn't guaranteed
- add extra test to verify that a send message is received even if the Stream is already closed
- changed OutGoing to Outgoing
- fixed a bug that `metrics.tick()` was never called
- removed 2 unused nightly features and added `deny_code`
data associated with a character, rather than individually as we were
planning to do with stats/inv/etc... This removes potential for DB locking when we deal with each individually, and we
should have plenty of room for additional writes within the transaction.
big combined updates.
- Add a timer to the stats persistence system and change the frequency
that it runs to 10s
- Seperate the loading of character data for the character list during
selection, and the full data we will grab during state creation. Ideally
additional persisted bits can get returned at the same point and added
to the ecs within the same block.
- Update client code to use persisted stats
- Add a system for stats persistence
- Add a basic scheduler to control duration between execution of
persistence systems
- Make the character screen load with an empty character list from the server, send event to the server for character creation with data, but not yet saving them to the DB.
- Working but messy character saving to DB
- Add the character_data to the client, rather than keep it in the GLobalState.
