Compute shaders

[tombh]

Apologies if this is already addressed elsewhere. Is it posible or is it planned to be possible, to build computer shaders? Like this for example? https://github.com/EmbarkStudios/rust-gpu/tree/main/examples/shaders/compute-shader

This should be entirely possible; the machinery is all there on the rust-gpu side, and storage buffers are supported now via patched dependency forks, so the only issue I forsee is having to manually retrieve the raw Handle<Shader> from inside bevy-rust-gpu's combined SPIR-V + metadata asset rather than it being fully automatic as per the Material stuff.

Compute pipelines are fairly low-level in bevy at the moment, so it's a matter of building out the pipeline machinery as per one of the official examples and passing it said Handle<Shader>.

I've opened bevy-rust-gpu/#20 to track the process of building a proper example.

That's great, thank you ❤️
