CGAL::Loop_mask_3< Polyhedron_3 > Class Template Reference
3D Surface Subdivision Methods

#include <CGAL/Subdivision_mask_3.h>

Definition

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. Loop_mask_3 implements the geometry masks of Loop subdivision on a triangulated Polyhedron_3<Cartesian>.

Template Parameters
Polyhedron_3must be a CGAL::Polyhedron_3 instantiated with a Cartesian kernel, which defines the Point_3 for the vertices.
