Contact recycling is a technique I developed for Box2D and Box3D. Contact recycling can drastically improve rigid body simulation performance, making the process of computing contact points almost fre...

The separating axis test (SAT) works well for computing contact manifolds. Unlike GJK, it is robust when shapes are very close together and it works when shapes are overlapped. Box3D uses SAT for comp...
