CGAL 5.5.1  3D Triangulation Data Structure

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 Software Design.)
Creation
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.
Types  
The class  
typedef unspecified_type  Point 
Optional for the triangulation data structure alone.  
typedef TriangulationDataStructure_3  Triangulation_data_structure 
typedef TriangulationDataStructure_3::Vertex_handle  Vertex_handle 
typedef TriangulationDataStructure_3::Cell_handle  Cell_handle 
Access Functions  
Cell_handle  cell () const 
Returns a cell of the triangulation having v as vertex.  
Point  point () const 
Returns the point stored in the vertex. More...  
Setting  
void  set_cell (Cell_handle c) 
Sets the incident cell to c .  
void  set_point (const Point &p) 
Sets the point to p . More...  
Checking  
bool  is_valid (bool verbose=false) const 
This is a function for debugging purpose. More...  
bool TriangulationDataStructure_3::Vertex::is_valid  (  bool  verbose = false  )  const 
This is a function for debugging purpose.
Checks the validity of the vertex. Must check that its incident cell has this vertex. The validity of the base vertex is also checked.
When verbose
is set to true
, messages are printed to give a precise indication on the kind of invalidity encountered.
Point TriangulationDataStructure_3::Vertex::point  (  )  const 
Returns the point stored in the vertex.
Optional for the triangulation data structure alone.
void TriangulationDataStructure_3::Vertex::set_point  (  const Point &  p  ) 
Sets the point to p
.
Optional for the triangulation data structure alone.
