The concept TriangulationDataStructure_3::Vertex represents the vertex class of a 3Dtriangulation data structure. It must define the types and operations listed in this section. Some of these requirements are of geometric nature, they are optional when using the triangulation data structure class alone. They become compulsory when the triangulation data structure is used as a layer for the geometric triangulation class. (See Section 28.2.)
 
Optional for the triangulation data
structure alone.

The class TriangulationDataStructure_3::Vertex defines types that are the same as some of the types defined by the triangulation data structure class TriangulationDataStructure_3.
 


 


 

In order to obtain new vertices or destruct unused vertices, the user must call the create_vertex() and delete_vertex() methods of the triangulation data structure.

 Returns a cell of the triangulation having v as vertex. 

 Returns the point stored in the vertex. Optional for the triangulation data structure alone. 

 Sets the incident cell to c. 

 Sets the point to p. Optional for the triangulation data structure alone.
