## CGAL::Triangulation_ds_vertex_base_3<>

### Definition

The class Triangulation_ds_vertex_base_3 can be used as the base vertex for a 3D-triangulation data structure, it is a model of the concept TriangulationDSVertexBase_3.

Note that if the triangulation data structure is used as a parameter of a geometric triangulation (Section and Chapter ), then the vertex base class has to fulfill additional geometric requirements, i.e. it has to be a model of the concept TriangulationVertexBase_3.

This base class can be used directly or can serve as a base to derive other base classes with some additional attributes (a color for example) tuned for a specific application.
