Cb.
The class Delaunay_triangulation_cell_base_with_circumcenter_3 derives from Cb, a cell base class of a 3D triangulation.
It provides an easy way to cache the computation of the circumcenters of tetrahedra. Note that input/output operators discard this additional information.
All functions modifying the vertices of the cell invalidate the cached circumcenter.
| Traits | is the geometric traits class and must be a model of DelaunayTriangulationTraits_3. |
| Cb | is a cell base class from which Delaunay_triangulation_cell_base_with_circumcenter_3 derives. Cb should be a model of DelaunayTriangulationCellBase_3. It has the default value Delaunay_triangulation_cell_base_3<Traits>. |

| typedef Traits::Point_3 | Point |
Access function | |
As a model of the concept If it has already been computed in the past, the cached value is returned. | |
| const Point & | circumcenter (Traits >=Traits()) const |
| Computes the circumcenter of the tetrahedron, or retrieves it if already computed. | |
