In this episode I explain what a collision manifold is, and why we will need it in our physics engine. I go over the three key features of the collision manifold: the collision normal, the contact points, and the depth. Then, I go over how to find a collision manifold for 2 colliding circles. Finally we actually code an implementation of this and add it to the physics engine.
