#include <CGAL/Subdivision_mask_3.h>
A stencil determines a source neighborhood whose points contribute to the position of a refined point.
The geometry mask of a stencil specifies the computation on the nodes of the stencil. CatmullClark_mask_3
implements the geometry masks of Catmull-Clark subdivision on a CGAL::Polyhedron_3<Cartesian>
.
Polyhedron_3 | must be a CGAL::Polyhedron_3 instantiated with a Cartesian kernel, which defines the Point_3 for the vertices. |
