pbr shader cleanup (#10105) # Objective cleanup some pbr shader code. improve shader stage io consistency and make pbr.wgsl (probably many people's first foray into bevy shader code) a little more human-readable. also fix a couple of small issues with deferred rendering. ## Solution mesh_vertex_output: - rename to forward_io (to align with prepass_io) - rename `MeshVertexOutput` to `VertexOutput` (to align with prepass_io) - move `Vertex` from mesh.wgsl into here (to align with prepass_io) prepass_io: - remove `FragmentInput`, use `VertexOutput` directly (to align with forward_io) - rename `VertexOutput::clip_position` to `position` (to align with forward_io) pbr.wgsl: - restructure so we don't need `#ifdefs` on the actual entrypoint, use VertexOutput and FragmentOutput in all cases and use #ifdefs to import the right struct definitions. - rearrange to make the flow clearer - move alpha_discard up from `pbr_functions::pbr` to avoid needing to call it on some branches and not others - add a bunch of comments deferred_lighting: - move ssao into the `!unlit` block to reflect forward behaviour correctly - fix compile error with deferred + premultiply_alpha ## Migration Guide in custom material shaders: - `pbr_functions::pbr` no longer calls to `pbr_functions::alpha_discard`. if you were using the `pbr` function in a custom shader with alpha mask mode you now also need to call alpha_discard manually - rename imports of `bevy_pbr::mesh_vertex_output` to `bevy_pbr::forward_io` - rename instances of `MeshVertexOutput` to `VertexOutput` in custom material prepass shaders: - rename instances of `VertexOutput::clip_position` to `VertexOutput::position` 2023-10-13 19:12:40 +00:00			`#import bevy_pbr::forward_io VertexOutput`
Configurable colors for wireframe (#5303) # Objective - Make the wireframe colors configurable at the global level and the single mesh level - Based on https://github.com/bevyengine/bevy/pull/5314 This video shows what happens when playing with various settings from the example https://github.com/bevyengine/bevy/assets/8348954/1ee9aee0-fab7-4da8-bc5d-8d0562bb34e6 ## Solution - Add a `color` field to the `WireframeMaterial` - Use a `WireframeColor` component to configure the color per entity - Add a `default_color` field to `WireframeConfig` for global wireframes or wireframes with no specified color. ## Notes - Most of the docs and the general idea for `WireframeColor` came from [UberLambda](https://github.com/UberLambda) in #3677 but the code ended up completely different so I created a separate branch. ~~I'm not sure how to correctly credit them on this PR.~~ (I re-created the commit but I added them as co-author in the commit message) ~~Closes https://github.com/bevyengine/bevy/pull/3677~~ ~~Closes https://github.com/bevyengine/bevy/pull/5301~~ ~~https://github.com/bevyengine/bevy/pull/5314 should be merged before this PR.~~ 2023-10-13 00:06:24 +00:00			`struct WireframeMaterial {`

update wireframe rendering to new renderer (#3193) Updates the wireframe rendering initialliy implemented in https://github.com/bevyengine/bevy/pull/562 to the new renderer. It lives in `bevy_pbr2` instead of `bevy_render2` because that way it can reuse the `MeshPipeline`. 2021-12-10 21:09:36 +00:00

update wgpu to 0.13 (#5168) # Objective - Update wgpu to 0.13 - ~~Wait, is wgpu 0.13 released? No, but I had most of the changes already ready since playing with webgpu~~ well it has been released now - Also update parking_lot to 0.12 and naga to 0.9 ## Solution - Update syntax for wgsl shaders https://github.com/gfx-rs/wgpu/blob/master/CHANGELOG.md#wgsl-syntax - Add a few options, remove some references: https://github.com/gfx-rs/wgpu/blob/master/CHANGELOG.md#other-breaking-changes - fragment inputs should now exactly match vertex outputs for locations, so I added exports for those to be able to reuse them https://github.com/gfx-rs/wgpu/pull/2704 2022-07-14 21:17:16 +00:00			`@fragment`
