introduce Terrain and Territory
fix merge mistakes
only `localhost` are allowed in a release build.
when debug assertions are on, others are also allowed.
This change undoes the changes to the settings, so compared to master, there is no effect
The auth server no longer allows the protocol to be specified. we enforce `https` for the auth server, so DO NOT provide a auth url with `https://` but without.
correct is now `auth.veloren.net`
incorrect is: `https://auth.veloren.net`
lagging a bit behind on terrain. Which is fine. Block Places and Block Pickup are not handled in this stream, as they go through the standart route of event handling.
Instead of keeping Runtime and manually spawn a task on `drop` this task is spawned at start and will wait to be triggered.
The `drop` methods then wait for completion, UNLESS they are in a async context, then they MUST NOT BLOCK (deadlock potential), so they defer it to the Runtime and HOPE for the runtime to exist long enough.
This get rid of the weird `block_in_place` which is only accessable with `rt-multi-threaded` and has some disadvantages.
We also wont requiere the runtime to be active all the time. Though its needed for a clean shutdown
- now last digit version is compatible 0.6.0 will connect to 0.6.1
- the TCP DATA Frames no longer contain START field, as it's not needed
- the TCP OPENSTREAM Frames will now contain the BANDWIDTH field
- MID is not Protocol internal
Update network
- update API with Bandwidth
Update veloren
- introduce better runtime and `async` things that are IO bound.
- Remove `uvth` and instead use `tokio::runtime::Runtime::spawn_blocking`
- remove futures_execute from client and server use tokio::runtime::Runtime instead
- give threads a Name
- completly switch to Bytes, even in api. speed up TCP by fak 2
- improve benchmarks
- speed up mpsc metrics
- gracefully handle shutdown by interpreting Ok(0) as tokio::tcpstream closed now.
- fix hotloop in participants by adding `Some(n)` to fix endless handing.
- fix closing bug by closing streams after `recv_mgr` is shutdown even if now shutdown is triggered locally.
- fix prometheus
- no longer throw when a `Stream` is dropped while participant still receives a msg for it.
- fix the bandwith handling, TCP network send speed is up to 1.5GiB/s while recv is 150MiB/s
- add documentation
- tmp require rt-multi-threaded in client for tokio, to not fail cargo check
this is prob stable, i tested over 1 hour.
after that some optimisations in priomgr.
and impl. propper bandwith.
Speed is up to 2GB/s write and 150MB/s recv on a single core
sync add documentation
- better logging in network
- we now notify the send of what happened in recv in participant.
- works with veloren master servers
- works in singleplayer, using a actual mid.
- add `mpsc` in whole stack incl tests
- speed up internal read/write with `Bytes` crate
- use `prometheus-hyper` for metrics
- use a metrics cache
- Implementing a async non-io protocol crate
a) no tokio / no channels
b) I/O is based on abstraction Sink/Drain
c) different Protocols can have a different Drain Type
This allow MPSC to send its content without splitting up messages at all!
It allows UDP to have internal extra frames to care for security
It allows better abstraction for tests
Allows benchmarks on the mpsc variant
Custom Handshakes to allow sth like Quic protocol easily
- reduce the participant managers to 4: channel creations, send, recv and shutdown.
keeping the `mut data` in one manager removes the need for all RwLocks.
reducing complexity and parallel access problems
- more strategic participant shutdown. first send. then wait for remote side to notice recv stop, then remote side will stop send, then local side can stop recv.
- metrics are internally abstracted to fit protocol and network layer
- in this commit network/protocol tests work and network tests work someway, veloren compiles but does not work
- handshake compatible to async_std
switch to `tokio` and `async_channel` crate.
I wanted to do tokio first, but it doesnt feature Sender::close(), thus i included async_channel
Got rid of `futures` and only need `futures_core` and `futures_util`.
Tokio does not support `Stream` and `StreamExt` so for now i need to use `tokio-stream`, i think this will go in `std` in the future
Created `b2b_close_stream_opened_sender_r` as the shutdown procedure does not need a copy of a Sender, it just need to stop it.
Various adjustments, e.g. for `select!` which now requieres a `&mut` for oneshots.
Future things to do:
- Use some better signalling than oneshot<()> in some cases.
- Use a Watch for the Prio propergation (impl. it ofc)
- Use Bounded Channels in order to improve performance
- adjust tests coding
bring tests to work
* Remove tweak feature

* Update all other dependencies automatically based on these changes
* Update gilrs to latest at the request of Ada Lovegirls
* Update meshing benchmarks to new criterion API
- Separate `invite` machinery from `group_manip` into it's own thing (includes renaming `group_invite` to `invite` where applicable).
- Move some invite/trade machinery to `ControlEvent`.
- Make `TradePhase` a proper enum instead of a bunch of bools.
- Make `TradeId` a proper newtype.
- Remove trades from `Trades` on accept (previously was only on decline).
- Typo fixes/misc cleanup.
- Add bullet point for trading to the changelog.
- Fix item swapping edge case

- Use `Client::current` in `Client::is_dead`
- Accept/decline buttons that submit the proper messages
- A phase2 screen that renders the (item, quantity) pairs as text
- More checks in the trade state machine server-side.
this tests the broad api of veloren and FAILS in case the interface is changed. It contains a not that those functions are commonly used by 3rd parties
and thus they need to be notified
* Improved server error message for character load errors.
* Added server logging for item asset load errors during character load.
* Fixed character select error message dialog not supporting long messages.
player buffs animation
more testing debuffs
sorting and display limit fix
overhead buffs

WIP buff removal function
fmt
Update buffs.rs
Now with compiling: WIP group UI buffs
positioning
Update group.rs
Update group.rs
Small optimizations.
Fixed positioning of buffs in group panel. Broke buff tooltips in group panel.
buff frame visuals
added setting for displaying buffs at minimap
So first off all we had to update the toolchain, i think everything in september is okay, but we got with this current version.
Then we had to update several dependencies, which broke:
- need a specific fix of winit, i think we want to get rid of this with iced, hopefully, because its buggy as hell. update wayland client to 0.27
- use a updated version of glutin which has wayland-client 0.27 and no longer the broke version 0.23
- update conrod to use modern copypasta 0.7
- use `packed_simd_2` instead of `packed_simd` as the owner of the create abandoned the project.
- adjust all the coding to work with the newer glutin and winit version. that also includes fixing a macro in one of the dependencies that did some crazy conversion from 1 event type to another event type.
It was called `convert_event`
- make a `simd` feature which is default and introduce conditional compiling.
AS I HAVE NO IDEA OF SIMD AND THE CODE. AND I DIDN'T INTRODUCE THE ERROR IN THE FIRST PLACE, WE PANIC FOR NON SIMD CASE FOR NOW. BUT IT WORKS FOR TESTS.
- tarpaulin doesnt support no-default-features. so we have to `sed` them away. semms fair.
His reason to reqeust that is, that there might not be a perfect disctinction in the future.
Now we need to send ServerGeneral over streams and do additional checking at various places to verify that not the wrong variant is send.
- Instread we have a dedicated thread that will async wait for new participants to connect and then notify the main thread
- registry no longer sends a view distance with it.
- remove ClientMsg::Command again as it's unused
```
//This is a helper structure, containing all possible data send over
pub enum ClientMsg {
Initial(ClientType),
General(ClientGeneralMsg),
InGame(ClientInGameMsg),
NotInGame(ClientNotInGameMsg),
Register(ClientRegisterMsg),
Ping(PingMsg)
}
```
Rather than having a single Stream to handle ALL data, seperate into multiple streams:
- Ping Stream, for seperate PINGS
- Register Stream, only used till the client is registered, then no longer used!
- General Stream, used for msg that can occur always
- NotInGame Stream, used for everything NOT ingame, e.g. Character Screen
- InGame Stream, used for all GAME data, players, terrain, entities, etc...
This version does compile, and gets the client registered (with auth too) but doesnt get to the char screen yet.
This fixes also the ignoring messages problem we had, as we are not sending data to the register stream!
This fixes also the problem that the server had to sleep for the Stream Creation, as the Server is now creating the streams and client has to sleep.
Add a basic random feature to char creation
loading screen bg (part 2)
loading screen changes, random button graphics
Random appearance also pick a random npc name
- Compression is no longer enabled always but can now be enabled per Stream.
If a Stream is Compression enabled it will compress and decompress all msg (except for `raw` access) before handling them internally.
You need to handle compression yourself for `raw` fn.
- added a new feature to the network crate to enable or disable the compression
- switched to `lz-fear` instead of `lz4-compression`
- use `bitflags` to represent the `Promises` struct
Till now, we just dropped the TCP connection and registered this as a clean shutdown.
The prodocol reader intereted this and send a Frame::Shutdown frame to it's local processor.
This is ofc wrong.
So now the protocol reader will detect a Frame::Shutdown frame and send it over. if the Tcp connection gets closed it will return an Error up.
The processor will then pick up this error and request a unclear shutdown and notifies the user.
Also when doing a clean shutdown we are sending a Frame::Shutdown now to the remote side to trigger this behavior.
Before we wrongly added the feature of only using a `select` in channel. This is WRONG,
as it could mean that the write maybe fails, but the read still had some Frames buffered which then get dropped.
Its fixed now by the clean shutdown mechanims defined before.
Also when a channel is closed now inside a participant we are closing the whole participant as a protection.
However, we must not close the recv channel as the `handle_frames_mgr` might still be working on them, so we only stop writing/sending.
Debugging this also let me introduce some smaller fixes:
- PID in tests are now 0 and 1+1*64+1*64*64+... this makes the traces appear as AAAAAA and BBBBBB instead of ABAAAA and ACAAAA
- veloren client now better seperates between clean shutdown and unclear shutdown.
- added a new type: C2pFrame for `(cid, Result<Frame, ()>)`
- wrong frames inside the handshare are not counted in metrics

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.

- 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).

- 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.

- 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.

Hotloading colors, part 1: colors in common.
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.

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.

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).

Making maps brighter.

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.
