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

#include <CGAL/Subdivision_mask_3.h>


The full template declaration of Loop_mask_3<Polyhedron_3> states one template parameter:

template < class Polyhedron_3> class Loop_mask_3;

The only parameter requires a Polyhedron_3 as the argument. The Polyhedron_3 should be specialized with the Cartesian kernel, which defines the Point_3 for the vertices.

default constructor.

Stencil functions

void L.edge_node ( Edge_handle e, Point_3& pt)
computes the Loop edge-point pt of the edge e.

void L.vertex_node ( Vertex_handle v, Point_3& pt)
computes the Loop vertex-point pt of the vertex v.

void L.border_node ( Halfedge_handle e, Point_3& ept, Point_3& vpt)
computes the Loop edge-point ept and the Loop vertex-point vpt of the border edge e.
