## CGAL::Triangulation_vertex_base_3<TriangulationTraits_3, TriangulationDSVertexBase_3>

### Definition

The class *Triangulation_vertex_base_3* is a model of the concept
*TriangulationVertexBase_3*, the base vertex of a 3D-triangulation.
This class stores a point.

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

*#include <CGAL/Triangulation_vertex_base_3.h>*

### Parameters

The first template argument is the geometric traits class
*TriangulationTraits_3* which provides the point type, *Point_3*.
Users of the geometric triangulations (Section 28.2 and
Chapter 27) are strongly advised to use the same
geometric traits class *TriangulationTraits_3* as the one used for
*Triangulation_3*. This way, the point type defined by the base vertex is
the same as the point type defined by the geometric traits class.

The second template argument is a combinatorial vertex base class from which
*Triangulation_vertex_base_3* derives.
It has the default value *Triangulation_ds_vertex_base_3<>*.
