  Generate(d) custom libraries for geometric algebras

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?

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.

  Rust bindings for ROS 2

  

I want to make this happen ! Do you know of any good robotics framework in Rust, as of today ? I heard that ROS2 was slowly including Rust [1], not sure at how did it go. Ros would be a good entry door to sensor fusion, mapping and localization. Because all of the hardware integration / abstraction is already done (in C++). I'm curious to know if company are using this.

  Visualize streams of multimodal data. Fast, easy to use, and simple to integrate. Built in Rust using egui.

  

Maybe the folks at Rerun [1] know something about it? I imagine at least some of their customers are Rust robotics shops.

  Minimal ROS 2 Rust bindings

  

You can also check https://github.com/sequenceplanner/r2r for ROS2 bindings (using in production at work for a couple of ROS nodes).

But TBH, in a Rust world, it’s worth revisiting the assumptions behind the ROS node architecture, since Rust is so strong at scaling to large monolithic applications (due to the strict hierarchical code patterns it encourages).

A transitional Rust approach, that doesn't try to reimplement everything from scratch, could do something like a strangler pattern: Take each ROS node, run them separately in “jails” with a Rust API around each one, then implement the plumbing/management logic in pure Rust.
