Other people have mentioned ray-tracing in one weekend
If anyone is really interested in graphics I would also recommend TinyRenderer
https://github.com/ssloy/tinyrenderer/wiki
This one is a CPU-based rasterizing renderer
Its good if you want to get a good understanding of what a GPU does underneath

Tiny raytracer and the related tiny series are pretty good implementations of certain popular rendering techniques, without the use of an API.

Project mention: A look at how Discord uses Rust for their data services | /r/rust | 2023-03-07

We only have one service we've written in go that we maintain, which is the media proxy. We will probably rewrite that in Rust at some point - but it's not a priority, and more of a passion/side project. Most of that service is actually open sourced here: https://github.com/discord/lilliput - it's basically just a CGO wrapper around C/C++ image resizing code. The closed source bits are just the code that downloads and feeds images to that library, then serves the results back over http/grpc.

Project mention: Www Which WASM Works | news.ycombinator.com | 2023-09-24

The problem is that the instructions for actually running the WASM file are not that clear... the docs the author mentions shows how to compile to WASM, which is easy enough, but then here's the instructions to make that actually work in the browser:
https://github.com/libjxl/libjxl/blob/main/tools/wasm_demo/R...
Yeah, you need some mysterious Python script, a JS service worker at runtime, choose whether you want the WASM or WASM_SIMD target, use a browser that supports Threads and SIMD if you chose that, make sure to serve everything with the appropriate custom HTTP headers... just reading that, I can see that to get this stuff working on non-browser WASM targets would likely require expertise in WASM, which is the point of the OP. WASM's UX is just not there yet.
