gpgpu-rs VS learn-wgpu

If you don't mind using a pure rust "alternative" you could use wgpu or a wrapper like gpgpu-rs, or any other of the projects mentioned in the other comments.

gpgpu-rs is a wgpu helper lib

You could try gpgpu-rs, a compute-focused framework I'm writing. It has some nice integrations with image and ndarray (tho the latter still needs some work) I'll definitely love some feedback :)

Would be really nice to have an actual cross platform GPGPU library. It's really holding every kind of progress back to have only vendor lock-in.

Maybe WebCPU will be capable of compute to the extend that CUDA isn't necessary. https://github.com/UpsettingBoy/gpgpu-rs

gpgpu-rs it is then! 🙂

I'm working on a compute framework (gpgpu-rs) based on wgpu, if you wanna check out.

My recommendation is to stick with WGSL for wgpu. I have some simple compute shaders examples if you wanna check out.

Nice.

Speaking of Snake game, if you want to go even deeper, you can try to use the wgpu crate to combine Rust and WebGPU to write everything from scratch. Here is the tutorial:

I once wrote a code editor with wgpu, from font rendering to char/line state management (very rough) for music live coding:

It runs in browsers, even including Safari!

https://sotrh.github.io/learn-wgpu/ This is probably the best resource out there for learning wgpu specifically. If you're unfamiliar with graphics, the learnopengl one is good. If you've got experience though, jumping right into that one is a shout or looking at some vulkan ones as they're pretty similar in terms of architecture.

Most of The WGPU I learnt is from https://sotrh.github.io/learn-wgpu/ but it doesn't really talk about designing n stuff, I thought of checking out the source code for Bevy or even games like veloren. But well, their codebases are pretty big to get started in the first place.

So I was wondering if opting for option 1 would be better to begin with. OpenGL has a much bigger community and wgpu only has its documentation which I hear is not quite up there yet. There is this excellent tutorial for wgpu that I read through, but it seems like wgpu can be a lot more complicated than starting with OpenGL.

I started with wgpu tutorial (https://sotrh.github.io/learn-wgpu/) since I like the idea of portability and it's a Rust-first library, but it seems I'm missing some foundations of how CG works in general: the code is given, a little of explanation like it assumes I already know something, maybe I'm wrong, but I wish there was a longer explicit version.

If you haven't seen it: https://sotrh.github.io/learn-wgpu/ is a good introduction that will explain most of what you asked, then can refer to rend3d or bevys renderer to see how a render graph works.
