PTQMask_3

Required member functions for the PTQMask_3 concept. This policy concept of geometric computations is used in CGAL::Subdivision_method_3::PTQ<Polyhedron_3, Mask>.

void	mask.edge_node ( Edge_handle e, Point_3& pt)
		computes the edge-point pt based on the neighborhood of the edge e.

void	mask.vertex_node ( Vertex_handle v, Point_3& pt)
		computes the vertex-point pt based on the neighborhood of the vertex v.

void	mask.border_node ( Halfedge_handle e, Point_3& ept, Point_3& vpt)
		computes the edge-point ept and the vertex-point vpt based on the neighborhood of the border edge e.
