Detailed Description

Collision detection functor which uses recommended collision functions.

Calculates and stores contact information between two particles. If a collision was successfully detected by the operator() contactPoint, contactNormal and penetrationDepth contain the contact information. If no collision was detected the values of these variables is undefined!
