vange-rs VS learn-wgpu

This is a new rendering method I was working on in Rusty Vangers. It's based on using a hierarchical voxel grid (mipmapped 3D texture) as an acceleration structure for ray tracing. Allows viewing the level from any perspective, and is faster than the "painter" method.

You don't need to depend on Angle in the build system, or link to it statically. For the purposes of your program it's just a GL driver. You'd just take libEGL.dll and a few dependencies from somewhere and place it in your folder with the executable. You can either copy it from Chrome or Firefox distribution, or as an artifact from https://github.com/DileSoft/gfbuild-angle, which my friend has set up for http://vange.rs/ builds on older Windows.

I couldn't find any mention of it in the official documentation or online, and I looked in some repositories online until I saw something suspicious here where there is a comment mentioning an include.

This is a port of vange-rs on "wasm32-unknown-emscripten" target via wgpu's GLES3 backend. Done by @caiiiycuk (thank you!), and also described in https://habr.com/en/post/594611/ (in Russian language).

P.S. I'm fully using WGSL in vange-rs and baryon

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:

https://github.com/glicol/glicol-wgpu

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.
