Definition

template<class PolygonMesh, class VertexPointMap = typename boost::property_map<PolygonMesh, vertex_point_t>::type>
class CGAL::Upsample_mask_3< PolygonMesh, VertexPointMap >

TODO: need to find the correct name for this scheme, if it exists.

And also complete the documentation.

The geometry mask of Upsample subdivision. This does not change the geometry of the mesh. In other words, the original vertices are not moved, and the new vertices are the average of the incident vertices. This is useful for increasing the resolution of a mesh without changing its geometry.

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. Upsample_mask_3 implements the geometry masks of Upsample subdivision on a triangulated model of MutableFaceGraph, such as Polyhedron_3 and Surface_mesh.

Template Parameters

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

Is model of

PTQMask_3
