Keyboard: Space toggles play, R resets, ] steps forward, [ returns to the initial state.

A hybrid Rapier3D and Three.js mechanics simulation for comparing off-center sphere collisions. Rapier3D computes contacts and rigid-body motion, while Three.js renders the lab plane, depth cues, trails, and velocity/momentum vectors.
