HN comment orderI've played with GA for a while, bought a couple of books, enjoyed the math, experimented with writing my own library. But, as TTProgram's comment, I've yet to find an application where it clearly improves on high-school vectors. I'm aware that Geomerics purportedly used it for doing global illumination calculations, but there was scant specifics (understandably) about the actual implementation. So we don't know in what capacity it was used. I've heard it praised for physics applications, but I haven't…
I went a little off the deep end a bunch of years ago learning geometric algebra. For a similar, but slightly different and cool take, check this out [0]. It's a take on multivectors, dyadics, and differential forms, which really shine in E&M. It's a shame this isn't taught to undergrads with linear algebra and vector calc.
