## Definition

template<typename Traits, typename Vb>
class CGAL::Triangulation_on_sphere_vertex_base_2< Traits, Vb >

Is model of
  `TriangulationOnSphereVertexBase_2`

The class `Triangulation_on_sphere_vertex_base_2` is the default model for the concept `TriangulationOnSphereVertexBase_2` and the default vertex base class for triangulations on the sphere.

`Triangulation_on_sphere_vertex_base_2` can be simply plugged into 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_on_sphere_2`. 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_on_sphere_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<>`.
