Methods
Remarks
Contact filters are called in the narrow phase (in CollisionAlgorithms) to
post-process the found contacts. Example usages of a contact filter:
- Remove redundant contacts. Some applications, like rigid body physics, needs only a minimal set of contacts, e.g. only 4 contacts per ContactSet.
- Remove "bad" contacts, for example contacts where the normal direction points into an undesired direction.
- Merge contacts. For some applications it is useful to keep only one contact which is the average of all other contacts.
