Honestly, this is much easier in Geometric Algebra. You can operate in rotor space directly, in an analogous way to complex phase.

- Iwan-Zotow 4y agoGot some write-up on that?
- wasabi991011 4y agoLet's remove Quaternions from every 3D Engine[1] by Marc Ten Bosch (developer of 4D Toys and Meigakure) was my introduction to geometric algebra, and I remember it being a great explanation. [1] https://marctenbosch.com/quaternions/ https://marctenbosch.com/quaternions/
- nh23423fefe 4y agoPretty hard to follow along. Never really explained why treating H as R^4 doesn't work as an interpolation. The angle-axis seems like a weird hack to pretend you're in R^3 or something? GA is so conceptually beautiful.
