TriangulationHierarchyVertexBase_2 Concept Reference

Definition

The vertex of a triangulation included in a triangulation hierarchy has to provide some pointers to the corresponding vertices in the triangulations of the next and preceding levels. Therefore, the concept TriangulationHierarchyVertexBase_2 refines the concept TriangulationVertexBase_2, adding handles to the corresponding vertices in the next and previous level triangulations.

Refines:

TriangulationVertexBase_2

Operations
Vertex_handle	up ()
	returns the corresponding vertex (if any) of the next level triangulation.
Vertex_handle	down ()
	returns the corresponding vertex of the previous level triangulation.
void	set_up (Vertex_handle u)
	sets the handle pointing to to the corresponding vertex of the next level triangulation.
void	set_down (Vertex_handle d)
	sets the handle pointing to the corresponding vertex of the previous level triangulation.
