"high-level" and "based on C" in the same sentence? Something wrong isn't right.

Oooh, reminds me a bit of "Geometry types for graphics programming":

Have you looked into geometric algebra before? It has some nicer properties than linear algebra, and could potentially work a bit better with this kind of thing.

Oh my bad, I have—or at least, of bivectors and rotors: marctenbosch.com/quaternions/

Yeah that's what I was thinking of! I used to try to understand a textbook at uni that went through it. I feel like the explanations leave a bunch to be desired, but it seems a bit more composable than linear algebra…? But yeah I could be misguided here.

made a cool library for it in Rust! I think it avoids some of the performance pitfalls I used to read about in that old textbook:
Indeed, though uv only implements enough to replace quaternions, it doesn't implement the whole 3d projective geometric algebra. I've been meaning to do that for some time but havent got around to it. In c++ there is Klein by which is awesome jeremyong.com/klein/

Oooh coool! Was not aware of this library, thanks! 😊
