[Merged by Bors] - Add Distance and Atmospheric Fog support #6412

coreh · 2022-10-29T22:46:18Z

Objective

Add support for the “classic” distance fog effect, as well as a more advanced atmospheric fog effect.

Solution

This PR:

Introduces a new FogSettings component that controls distance fog per-camera.
Adds support for three widely used “traditional” fog falloff modes: Linear, Exponential and ExponentialSquared, as well as a more advanced Atmospheric fog;
Adds support for directional light influence over fog color;
Extracts fog via ExtractComponent, then uses a prepare system that sets up a new dynamic uniform struct (Fog), similar to other mesh view types;
Renders fog in PBR material shader, as a final adjustment to the output_color, after PBR is computed (but before tone mapping);
Adds a new StandardMaterial flag to enable fog; (fog_enabled)
Adds convenience methods for easier artistic control when creating non-linear fog types;
Adds documentation around fog.

Changelog

Added

Added support for distance-based fog effects for PBR materials, controllable per-camera via the new FogSettings component;
Added FogFalloff enum for selecting between three widely used “traditional” fog falloff modes: Linear, Exponential and ExponentialSquared, as well as a more advanced Atmospheric fog;

TIL you can embed SVG graphs inside of rustdoc!

I saw the Color constant docs that use styled <span>s and decided to give it a try, was also pleasantly surprised

Very cool, and the code and docs look good (caveat that I'm still learning rendering). I do wonder if we can make these more... modular? Having to include this sort of effect in bevy_pbr, and adding a bitflag to StandardMaterial definitely feels like it might get messy.

Is using pow 2.0 here really going to be competitive with another two multiplications? Do wgsl compilers optimize this for you?

No idea... If the WGSL doesn't do it, maybe the underlying GLSL/SPIRV/MSL compiler does?

Is there a good way to benchmark this? It probably adds up but hard to isolate in the middle of all of the other stuff the shader is doing

Hmm, unsure 🤔 Maybe try stress testing it on a very busy scene like animated foxes and then check the traces? Either way, this was mostly curiosity.

coreh · 2022-10-30T01:26:14Z

Thanks for the speedy CR! Added additional documentation comments.

I do wonder if we can make these more... modular? Having to include this sort of effect in bevy_pbr, and adding a bitflag to StandardMaterial definitely feels like it might get messy.

Maybe? There are already some things that affect, for example, lights that end up as bitflags there instead of special light-related components, so it's not completely out of place, but maybe there's indeed a cleaner way? I think what Wireframe is doing is maybe too heavy handed for this, but I'm new to the bevy way of doing things. Is there some precedent in how to modularize stuff like this?

Re: PBR shader, I added it there after some conversations on #rendering-dev on Discord, since if I understand it correctly depth-based post processing effects are not yet possible. (or not straightforward?) One benefit is that it allows us to handle fog on transparency correctly, which would be trickier with post processing.

I also got some feedback also in #rendering-dev about maybe moving Fog itself from a resource to a component, so that it can vary per-camera, not sure how to implement extraction for that case.

Yep, not a problem for this PR, but wanted to surface the idea so we start chewing on it.

I also got some feedback also in #rendering-dev about maybe moving Fog itself from a resource to a component, so that it can vary per-camera, not sure how to implement extraction for that case.

Oh I rather like that. IIRC there's an ExtractComponentPlugin that should point you in the right direction.

Allowing independent per-camera configuration

coreh · 2022-11-01T05:47:52Z

IIRC there's an ExtractComponentPlugin that should point you in the right direction.

Thanks! That was a good starting point.

Fog is now a Component and can be set independently per-camera. Here's a modified split_screen example running with two different fogs, one for each camera:

I also consolidated the fog setup code into a single FogPlugin.

Some ergonomics/usability questions:

Now that we can add/remove fog from cameras by simply adding and removing the component, does it still make sense to have a FogMode::Off variant? Is there some precedent to Components that are “added but disabled”, and does that feel idiomatic?
If we decide to keep the Off variant, should it still be the default? Or should we make one of the other variants a more “useful” out-of-the-box default?
Should we keep the short name Fog or make it something more specific (e.g. DistanceFog)? That's longer to type/remember but could makes sense in a future where there are other fog effects which are not added to the camera, but rather as separate, independent entities with Transform/GlobalTransform (e.g. LinearFog, SphericalFog or even VolumetricFog). That's kinda like lights work currently, naming-wise.

mockersf · 2022-11-01T08:43:05Z

Could you add an example that show off the various fog modes? Maybe cycle through them on a timer, or on a key press

JMS55 · 2022-11-01T18:50:37Z

I would remove the Off variant, and make the component not-added by default.
I would go with the more verbose option, something like DistanceFogSettings (and DistanceFogPlugin).

In general, this is the patterns I've been seeing for post-processing effects recently:

Make an ExamplePlugin plugin, that's either loaded by default as part of PbrPlugin (BloomPlugin), or optionally added by the user (FXAAPlugin)
Make an ExampleSettings component to be applied to any view you want the effect on, whose presence enables the effect and which holds the settings (no off switch on this component).
Optionally, add a setting to PbrPlugin or somewhere similar to globally toggle the effect off.

coreh · 2022-11-02T05:00:46Z

Added an interactive example, where you can tweak the parameters:

Fog.Example.mov

examples/3d/fog.rs

Otherwise the shader will fail compilation, since the `fog` uniform, defined in `bevy_pbr::mesh_view_bindings` will not be available, since that file is not imported by the prepass shader. (but `bevy_pbr::pbr_functions` is)

This is a really weird diff, what I did was actually just change the @binding numbers from 10, 11 to 11, 12.

Just rebasing and one minor change and I think this is good to go.

If I read #7356 correctly, these let must be changed to const once it i merged.

Thanks for the heads up, will keep an eye out.

robtfm

the documentation and examples are really excellent again.

a couple of copy/paste errors in the helpers and minor bits in the shader then LGTM

+    }


this block is repeated 4 times, can we move it up to pbr_functions (or make a function here for it)?

also i don't think we need the branch here but since it's a uniform branch maybe it's better to keep it anyway ..?

I also thought about lifting this out as it is common and instead just wrapping only the bits that change in a function. It's not incredibly clear whether it's an improvement though. If it looks better, please do it. If not, then I'm fine with not.

Just extracted it, it does look much cleaner.

## How This Works For the Bevy 0.10 release blog post (and for the first time ever), I'm publicly opening the doors to other people writing blog post sections. Specifically, if you worked on a feature in a substantial way and are interested in presenting it, you can now ask to claim a section by leaving a comment in this PR. If you claim a section, submit a pull request to the `release-0.10.0` branch in this repo. For the next week, we will be filling in sections (the release target is Saturday March 4th). Please don't claim a section if you don't plan on completing it within that timeline. Also don't claim a section if you weren't an active participant in the design and implementation of the change (unless you are a Maintainer or SME). I will claim any unclaimed sections. Try to match the style of previous release blog posts as much as possible. 1. Show, don't tell. Don't bombard people with information. Avoid large walls of text _and_ large walls of code. Prefer the pattern "byte sized description of one thing" -> "example code/picture/video contextualizing that one thing" -> repeat. Take readers on a journey step by simple step. 2. Don't use up reader's "mental bandwidth" without good reason. We can't afford page-long descriptions of minor bug fixes. If it isn't a "headliner change", keep the description short and sweet. If a change is self describing, let it do that (ex: We now support this new mesh shape primitive ... this is what it looks like). If it is a "headliner change", still try to keep it reasonable. We always have a lot to cover. 3. In slight competition with point (2), don't omit interesting technical information when it is truly fun and engaging. A good chunk of our users are highly technical and enjoy learning how the sausage is made. Try to strike a balance between "terse and simple" and "nerdy details". 4. When relevant, briefly describe the problem being solved first, then describe the solution we chose. This contextualizes the change and gives the feature value and purpose. 5. When possible, provide visuals. They create interest / keep people hooked / break up the monotony. 6. Record images and videos at the default bevy resolution (1280x720) 7. Provide an accurate listing of authors that meaningfully contributed to the feature. Try to sort in order of "contribution scale". This is hard to define, but try to be fair. When in doubt, ask other contributors, SMEs, and/or maintainers. 8. Provide numbers and graphs where possible. If something is faster, use numbers to back it up. We don't (yet) have automated graph generation in blog post style, so send data / info to me (@cart) if you want a graph made. ## Headliners Headliners are our "big ticket high importance / high profile" changes. They are listed briefly at the beginning of the blog post, their entries are roughly sorted "to the top", and they are given priority when it comes to "space in the blog post". If you think we missed something (or didn't prioritize something appropriately), let us know. * ECS Schedule v3 (previously known as "stageless") * Partial Android Support * Depth and Normal Prepass * Environment Map Lighting * Cascaded Shadow Maps * Distance and Atmospheric Fog * Smooth Skeletal Animation Transitions * Enable Parallel Pipelined Rendering * Windows as Entities * Renderer Optimizations * ECS Optimizations ## Sections These are the sections we will cover in the blog post. If a section has been claimed, it will have `(claimed by X)` in the title. If it is unclaimed it will have `(unclaimed)` in the title. Let us know if we missed a section. We don't cover every feature, but we should cover pretty much everything that would be interesting to users. Note that what is interesting or challenging to implement is not necessarily something that is relevant to our blog post readers. And sometimes the reverse is true! If you believe a section should be split up or reorganized, just bring it up here and we can discuss it. ### ~~Schedule V3 (claimed by @alice-i-cecile)~~ * [Migrate engine to Schedule v3][7267] * [Add `bevy_ecs::schedule_v3` module][6587] * [Stageless: fix unapplied systems][7446] * [Stageless: move final apply outside of spawned executor][7445] * Sets * Base Sets * [Base Sets][7466] * Reporting * [Report sets][7756] * [beter cycle reporting][7463] * Run Conditions * [Add condition negation][7559] * [And/Or][7605] * [Add more common run conditions][7579] * States * [States derive macro][7535] * System Piping Flexibility * [Support piping exclusive systems][7023] * [Allow piping run conditions][7547] ### ~~Depth and Normal Prepass (claimed by @IceSentry)~~ * [Add depth and normal prepass][6284] * [Move prepass functions to prepass_utils][7354] ### ~~Distance and Atmospheric Fog (claimed by @coreh)~~ * [Add Distance and Atmospheric Fog support][6412] ### ~~Cascaded Shadow Maps (claimed by @cart)~~ * [Cascaded shadow maps.][7064] * [Better cascades config defaults + builder, tweak example configs][7456] ### ~~Environment Map Lighting (claimed by @cart)~~ * [EnvironmentMapLight, BRDF Improvements][7051] * [Webgl2 support][7737] ### ~~Tonemapping options (claimed by @cart)~~ * [Initial tonemapping options][7594] ### ~~Android support + unification (claimed by @mockersf)~~ * [IOS, Android... same thing][7493] ### ~~Windows as Entities (claimed by @Aceeri)~~ * [Windows as Entities][5589] * [break feedback loop when moving cursor][7298] * [Fix `Window` feedback loop between the OS and Bevy][7517] ### ~~Enable Parallel Pipelined Rendering (claimed by @james7132)~~ * [Pipelined Rendering][6503] * [Stageless: add a method to scope to always run a task on the scope thread][7415] * [Separate Extract from Sub App Schedule][7046] ### ~~Smooth Skeletal Animation Transitions (claimed by @james7132)~~ * [Smooth Transition between Animations][6922] ### ~~Spatial Audio (claimed by @harudagondi)~~ * [Spatial Audio][6028] ### ~~Shader Processor Features (claimed by @cart)~~ * [Shader defs can now have a value][5900] * [Shaders can now have #else ifdef chains][7431] * [Define shader defs in shader][7518] ### ~~Shader Flexibility Improvements (claimed by @cart)~~ * [add ambient lighting hook][5428] * [Refactor Globals and View structs into separate shaders][7512] ### ~~Renderer Optimizations (claimed by @james7132)~~ * [bevy_pbr: Avoid copying structs and using registers in shaders][7069] * [Flatten render commands][6885] * [Replace UUID based IDs with a atomic-counted ones][6988] * [improve compile time by type-erasing wgpu structs][5950] * [Shrink DrawFunctionId][6944] * [Shrink ComputedVisibility][6305] * [Reduce branching in TrackedRenderPass][7053] * [Make PipelineCache internally mutable.][7205] * [Improve `Color::hex` performance][6940] * [Support recording multiple CommandBuffers in RenderContext][7248] * [Parallelized transform propagation][4775] * [Introduce detailed_trace macro, use in TrackedRenderPass][7639] * [Optimize color computation in prepare_uinodes][7311] * [Directly extract joints into SkinnedMeshJoints][6833] * [Parallelize forward kinematics animation systems][6785] * [Move system_commands spans into apply_buffers][6900] * [Reduce the use of atomics in the render phase][7084] ### ~~ECS Optimizations (claimed by @james7132 )~~ * [Remove redundant table and sparse set component IDs from Archetype][4927] * [Immutable sparse sets for metadata storage][4928] * [Replace BlobVec's swap_scratch with a swap_nonoverlapping][4853] * [Use T::Storage::STORAGE_TYPE to optimize out unused branches][6800] * [Remove unnecessary branching from bundle insertion][6902] * [Split Component Ticks][6547] * [use bevy_utils::HashMap for better performance.
