Snappets: a VR animation system based on Projective Geometric Algebra
summary
Snappets is a VR animation tool that records hand motions as transform compositions and creates spreadsheet entries, using Projective Geometric Algebra so points, planes and motions are all transforms. A demo builds a one‑eyed pirate whose eye follows a fish by snapping two sight lines and a hand rotation into a single rotor (a dual quaternions style rigid motion). The system extracts collision points and deflection angles via the geometric product, reportedly in three lines of code, and the live demo animations run successfully.
