20. Collision & Contact Physics
Computational collision detection prevents virtual solids from passing through one another. This chapter investigates the Gilbert-Johnson-Keerthi (GJK) algorithm, Expanding Polytope Algorithm (EPA) contact manifolds, Continuous Collision Detection (CCD) spatiotemporal sweeps, and speculative contact solvers.
