Conditionals and code generation performance

I noticed that a rust gpu shader was running much slower than the equivalent wgsl one. The wgsl one takes 53ms, and the rust gpu version takes 67ms. Looking at...

Ported shadertoy shader runs very slow (fractal pyramid)

6

I ported the shadertoy shader from https://www.shadertoy.com/view/tsXBzS to rust-gpu (code at https://github.com/LegNeato/rust-gpu/tree/fractal). When I run it, shadertoy on the web is way faster than rustgpu + wgpu locally, even with...

documentation and examples for porting WGSL/GLSL shaders

2

I've been porting some WGSL code like [like these](https://github.com/bevyengine/bevy/blob/main/assets/shaders/game_of_life.wgsl) into [rust](https://github.com/Bevy-Rust-GPU/example-workspace/pull/22#issuecomment-1796063937) and the documentation for actually writing shaders is very sparse: https://embarkstudios.github.io/rust-gpu/book/writing-shader-crates.html I only managed to get the above program...

This has been a long-time coming, I've mostly been putting it off because of how annoying it'd be to implement. (turns out I was a bit wrong and there's so...

`run-wasm` helper (`cargo-run-wasm`) for testing the wgpu runner on the web.

~~*Opening as draft because this is blocked on `wgpu::backend::web` being completely broken:*~~ * ~~https://github.com/gfx-rs/wgpu/issues/3430~~ * ~~the short version is that they made a `Copy` type convertible to a type that...

This is the idea I mentioned in: * https://github.com/EmbarkStudios/rust-gpu/issues/1086#issuecomment-1655044334 However, opening as draft because the situation is even messier than envisioned and more panic handling is needed (up to an...

*Opened as draft because it's somewhat incomplete, but I want it out of the way for now.* This PR adds a `TypedBuffer` "handle" type to `spirv-std` (comparable to `Image` types...

Using `arch::ignore_intersection` causes shader compilation to fail

### Expected Behaviour Shader crate successfully compiles ### Example & Steps To Reproduce ```rust #[spirv(any_hit)] pub fn my_any_hit() { let p = Vec3A::ZERO; if p.length_squared() < 1e-3 { unsafe {...

RuntimeArray as uniform creates invalid spv instead of erroring

1

### Expected Behaviour In the following example, you can't have a `uniform` with a variable amount of data, so it must be a `storage_buffer` instead. Currently, rust-gpu compiles it to...
