CGAL 6.0.1  2D Triangulations

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.
