Definition

template<class PolygonMesh, class VertexPointMap = typename boost::property_map<PolygonMesh, vertex_point_t>::type>
class CGAL::CatmullClark_mask_3< PolygonMesh, VertexPointMap >

The geometry mask of Catmull-Clark subdivision.

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 models of MutableFaceGraph, such as Polyhedron_3 and Surface_mesh.

Template Parameters

PolygonMesh	must be a model of the concept MutableFaceGraph.
VertexPointMap	must be a model of WritablePropertyMap with value type Point_3

Is Model Of:

PQQMask_3
