geometric_algebra VS crittershowdown

I got sucked down a Geometric Algebra rabbit hole a few months ago, which seems like a remarkably concise and intuitive way to work in a very wide variety of geometries, including 2D, 3D, 4D+, non-euclidean etc. I've wondered if GA would make a good foundation for a physics engine...

There are a few small rust libraries that look interesting [1][2], but none with a lot of traction.

Has anyone looked into this?

The GA community in general is very small. So yes, tooling could be better, but IMO that is not even the problem. The lack of understanding how to use it is, because GA is not explicitly taught in schools or universities.

I have written a compiler which generates SIMD ready code for the desired GAs. You can then use that output as a normal library for your application.

I built a game using Rapier! Using its deterministic mode, I built an online multiplayer game whereby players take turn slamming bugs against the other team and capture the hill.

It doesn't have a single-player mode yet (writing an AI for it is a bit more challenging than the chess-like I made) but check it out at https://evrimzone.itch.io/crittershowdown and the physics/game logic source code at https://github.com/evrimoztamur/crittershowdown/blob/e4d9a19....

I plan to write a post about how I wired it together and what I learned, but overall very solid library and well-thought of Rust-y API that enabled me to do everything I needed it to.
