`#include <CGAL/Triangulation_vertex_base_2.h>`

## Inherits from

Vb.

## Definition

The class `Triangulation_vertex_base_2` is the default model for the concept `TriangulationVertexBase_2`.

`Triangulation_vertex_base_2` can be simply plugged in the triangulation data structure of a triangulation, or used as a base class to derive other base vertex classes tuned for specific applications.

Template Parameters

  Traits | must be a geometric traits class which provides the type `Point`. It is strongly recommended to instantiate this traits class with the model used for the triangulation traits class. This ensures that the point type defined by `Triangulation_vertex_base_2` is the same as the point type defined by the triangulation.
  Vb | must be a model of the concept `TriangulationDSVertexBase_2` By default this parameter is instantiated by `Triangulation_ds_vertex_base_2<>`.

Is Model Of:
  `TriangulationVertexBase_2`
