CGAL::CatmullClark_mask_3<Polyhedron_3>

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. CatmullClark_mask_3<Polyhedron_3> implements the geometry masks of Catmull-Clark subdivision on a Polyhedron_3<Cartesian>.

#include <CGAL/Subdivision_mask_3.h>

Parameters

The full template declaration of CatmullClark_mask_3<Polyhedron_3> states one template parameter:

template <

class Polyhedron_3> class CatmullClark_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.

Creation

CatmullClark_mask_3<Polyhedron_3> CC;
	default constructor.

Stencil functions

void	CC.facet_node ( Facet_handle f, Point_3& pt)
		computes the Catmull-Clark facet-point pt of the facet f.
void	CC.edge_node ( Edge_handle e, Point_3& pt)
		computes the Catmull-Clark edge-point pt of the edge e.
void	CC.vertex_node ( Vertex_handle v, Point_3& pt)
		computes the Catmull-Clark vertex-point pt of the vertex v.
void	CC.border_node ( Halfedge_handle e, Point_3& ept, Point_3& vpt)
		computes the Catmull-Clark edge-point ept and the Catmull-Clark vertex-point vpt of the border edge e.
