Detailed Description

performs collision determination between two polyhedral surfaces

vtkCollisionDetectionFilter performs collision determination between two polyhedral surfaces using two instances of vtkOBBTree. Set the polydata inputs, the tolerance and transforms or matrices. If CollisionMode is set to AllContacts, the Contacts output will be lines of contact. If CollisionMode is FirstContact or HalfContacts then the Contacts output will be vertices. See below for an explanation of these options.

This class can be used to clip one polydata surface with another, using the Contacts output as a loop set in vtkSelectPolyData
