Definition

The concept TriangulationVertexBase_2 describes the requirements for the vertex base class of a triangulation data structure to be plugged in a basic, Delaunay or constrained triangulations.

The concept TriangulationVertexBase_2 refines the concept TriangulationDSVertexBase_2 adding geometric information: the vertex base of a triangulation stores a point.
