FYI, I recently posted about a 2d game I made, here: https://news.ycombinator.com/item?id=41761517

Putting aside the politics and all, focusing on the tech- one thing I came across when trying to do my own collision detection was the idea of using the GPU and occlusion queries for pixel-perfect results.

I didn't come up with the technique, but it's super cool, and since you're not taxing the GPU with tons of 3d triangles, it's perhaps a bit more free to do stuff like that.

Using the GPU is always interesting, although in my case I want to maintain compatibility with browsers through WebAssembly.

Nowadays, it’s very rare for a user to download and run a binary.

Ignorant question, but I assume that means there is no "browser-facing" or accessibility to the GPU for a web based application in this way (WebAssembled or even otherwise)?

There is WebGPU, but support isn’t widespread yet. Compared to WebGL it does allow you to create compute “shaders”

Yeah, the game I linked to is in Rust/wasm, running solely in browsers :)

The interesting part of the collision detection code is here: https://github.com/dakom/not-a-game/blob/main/src/collision/...
