This interface is made to be used by an iterative approach to do TimeOfImpact calculations This interface allows to query for closest points and penetration depth between two (convex) objects the closest point is on the second object (B), and the normal points from the surface on B towards A. distance is between closest points on B and closest point on A. So you can calculate closest point on A by taking closestPointInA = closestPointInB + m_distance * m_normalOnSurfaceB
