Detailed Description

See also: Class ICollision, Class CollisionPlane, Class CollisionSphere, Class CollisionVNormal, Class CollisionMesh, Class Box3, Class Point3, Class FPInterface

Description:: This class represents the operation interface to the collision detection system.

The interface ID is defined as COLLISION_FO_INTERFACE. To obtain a pointer to this interface you can use the macro GetCollisionOpsInterface(cd), which will return (CollisionOps )(cd)->GetFPInterface(COLLISION_FO_INTERFACE).
