## CGAL::Triangulation_face_base_2<Traits,Fb>

### Definition

The class Triangulation_face_base_2<Traits,Fb> is a model for the concept TriangulationFaceBase_2. It is the default face base class for basic and Delaunay triangulation.

These default base class can be used directly or can serve as a base to derive other base classes with some additional attribute (a color for example) tuned for specific applications.

### Parameters

The first template parameter of Triangulation_face_base_2<Traits,Fb> is a geometric traits class. The geometric traits is actually not used by the class.

The second template parameter has to be a model of the concept TriagulationDSFaceBase_2 and will serve as a base class for Triangulation_face_base_2<Traits,Fb> . CGALprovides a default instantiation for this parameter which is Triangulation_ds_face_base_2<>.
