CGAL 6.0 - dD Triangulations
|
The concept TriangulationVertex describes the requirements on the type used by the class CGAL::Triangulation<TriangulationTraits_, TriangulationDataStructure_>, and its derived classes, to represent a vertex.
TriangulationDSVertex We only list below the additional specific requirements of TriangulationVertex. Compared to TriangulationDSVertex, the main difference is the addition of an association of the vertex with a geometric point.
CGAL::Triangulation_vertex<TriangulationTraits_, Data, TriangulationDSVertex_> Input/Output
These operators can be used directly and are called by the I/O operator of class Triangulation.
CGAL::Triangulation_vertex<TriangulationTraits_, Data, TriangulationDSVertex_> TriangulationFullCell CGAL::Triangulation<TriangulationTraits_, TriangulationDataStructure_> Types | |
| typedef unspecified_type | Point |
| The type of the point stored in the vertex. | |
Creation | |
| TriangulationVertex (Full_cell_handle c, const Point &p) | |
Constructs a vertex with incident full cell c. | |
| TriangulationVertex (const Point &p) | |
| Same as above, but without incident full cell. | |
| TriangulationVertex () | |
Same as above, but with a default-constructed Point. | |
Operations | |
| void | set_point (const Point &p) |
The parameter p becomes the new geometrical position of the vertex. | |
| const Point & | point () const |
| Returns the vertex's position. | |
| std::istream & | operator>> (std::istream &is, TriangulationVertex &v) |
| Inputs the non-combinatorial information given by the vertex, i.e., the point and other possible information. | |
| std::ostream & | operator<< (std::ostream &os, const TriangulationVertex &v) |
| Outputs the non-combinatorial information given by the vertex, i.e., the point and other possible information. | |
The type of the point stored in the vertex.
It must be the same as the point type TriangulationTraits::Point_d when the TriangulationVertex is used in the class Triangulation<TriangulationTraits, TriangulationDataStructure_>.
| TriangulationVertex::TriangulationVertex | ( | Full_cell_handle | c, |
| const Point & | p | ||
| ) |
Constructs a vertex with incident full cell c.
The vertex is embedded at point p.
