CGAL 5.3 - Triangulated Surface Mesh Simplification
CGAL::Surface_mesh_simplification::Polyhedral_envelope_filter< GeomTraits, Filter > Class Template Reference

#include <CGAL/Surface_mesh_simplification/Policies/Edge_collapse/Polyhedral_envelope_filter.h>


The class Polyhedral_envelope_filter is a model for the PlacementFilter concept.

It rejects the placement if the nested filter rejects it, or if any triangle in the profile is not inside the polyhedral envelope, in this order.

Template Parameters
Filtermust be a model of the concept PlacementFilter. It defaults to a class that does not filter any placement.
Is Model Of:
