## 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 36.2 and
Chapter 35), 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.
