Thanks for the questions. Indeed many animation libraries store the quaternion and translation as separate components. There are a few reasons I use dual-quaternions in my own code. First, because I can "slerp" them, this means th

Yup, now that I've "swallowed the red pill" so to speak, I can't even look at quats/dual-quats in the same way. They are very much a small cross-section of something much bigger (more expressive/powerful/e

Yup that's a good suggestion. I actually don't even need to compile to wasm for much of it (I have it partially ported to GLSL already)

Thanks for the feedback. You may find https://www.jeremyong.com/klein/geometry-potpourri/ more approachable but I admit I don't have finalized material I'm completely satisfied with showing yet :( The ma

Thanks for the questions. > re: introductory materials The 3 links I compiled here ( https://www.jeremyong.com/klein/references/ ) I consider an absolute must for starting to consume GA. The book (ref #3) has one

Yes actually :) It took me a long time to actually decide to invest in GA because the sentiment I had was "it just replaces what I already know" and what I knew at the time was matrices, quaternions, and dual quaternions. It turns

Working on them! That said though, the audience of this article was originally meant to be animation engineers that have already "earned some stripes" and wanted to see the GA formulation.

I'm the author of Klein and was surprised to see a sudden burst of traffic so I checked the usual suspects and ended up here :) My goals for authoring Klein was to provide a library for performing all manner of geometric operations usi

Original author here, it is absolutely my goal that the library should be usable without needing to understand the ins and outs of GA. To this end, I've started adding a bunch of "helper" functions that do tasks like projecti
