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
