In PhysX, a material is the property of a physical object that defines the friction and restitution property of an actor, and is used to resolve the collision with other objects. To create a material, call
PxPhysics::createMaterial(), which requires three arguments of type
PxReal; these represent static friction, dynamic friction and restitution, respectively.
A typical example for creating a PhysX material is as follows:
PxMaterial* mMaterial = gPhysicsSDK->createMaterial(0.5,0.5,0.5);
