virtual void processCollision(const btCollisionObjectWrapper *body0Wrap, const btCollisionObjectWrapper *body1Wrap, const btDispatcherInfo &dispatchInfo, btManifoldResult *resultOut)
This class is not enabled yet (work-in-progress) to more aggressively activate objects.
btManifoldResult is a helper class to manage contact results.
virtual void * allocateCollisionAlgorithm(int size)=0
virtual btScalar calculateTimeOfImpact(btCollisionObject *body0, btCollisionObject *body1, const btDispatcherInfo &dispatchInfo, btManifoldResult *resultOut)
Used by the btCollisionDispatcher to register and create instances for btCollisionAlgorithm.
btCollisionObject can be used to manage collision detection objects.
