Definition

template<typename Traits, typename Cb>
class CGAL::Delaunay_triangulation_cell_base_with_circumcenter_3< Traits, 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.

Template Parameters

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>.

Is model of

DelaunayTriangulationCellBase_3

Types
typedef Traits::Point_3	Point

Access function
As a model of the concept DelaunayTriangulationCellBase_3, Delaunay_triangulation_cell_base_3 provides a circumcenter() member function. If it has already been computed in the past, the cached value is returned.
const Point &	circumcenter (Traits &gt=Traits()) const
	Computes the circumcenter of the tetrahedron, or retrieves it if already computed.
