Detailed Description

Raycast-CCD manager.

Raycast-CCD is a simple and potentially cheaper alternative to the SDK's built-in continuous collision detection algorithm.

This implementation has some limitations:

Also, since it is raycast-based, the solution is not perfect. In particular:

  • small dynamic objects can still go through the static world if the ray goes through a crack between edges, or a small hole in the world (like the keyhole from a door).
  • dynamic-vs-dynamic CCD is very approximate. It only works well for fast-moving dynamic objects colliding against slow-moving dynamic objects.

Finally, since it is using the SDK's scene queries under the hood, it only works provided the simulation shapes also have scene-query shapes associated with them. That is, if the objects in the scene only use PxShapeFlag::eSIMULATION_SHAPE (and no PxShapeFlag::eSCENE_QUERY_SHAPE), then the raycast-CCD system will not work.

Member Function Documentation

void RaycastCCDManager::doRaycastCCD ( bool  doDynamicDynamicCCD  ) 

Perform raycast CCD. Call this after your simulate/fetchResults calls.

Parameters:
[in] doDynamicDynamicCCD True to enable dynamic-vs-dynamic CCD (more expensive, not always needed)

bool RaycastCCDManager::registerRaycastCCDObject ( PxRigidDynamic actor,
PxShape shape 
)

Register dynamic object for raycast CCD.

Parameters:
[in] actor object's actor
[in] shape object's shape
Returns:
True if success
