Definition

template<typename Traits, typename Cb>
class CGAL::Regular_triangulation_cell_base_with_weighted_circumcenter_3< Traits, Cb >

The class Regular_triangulation_cell_base_with_weighted_circumcenter_3 derives from Cb, a cell base class of a 3D triangulation.

It provides an easy way to cache the computation of the weighted 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 RegularTriangulationTraits_3.
Cb	is a cell base class from which Regular_triangulation_cell_base_with_weighted_circumcenter_3 derives. Cb should be a model of RegularTriangulationCellBase_3. It has the default value Regular_triangulation_cell_base_3<RT>.

Is Model Of:

RegularTriangulationCellBaseWithWeightedCircumcenter_3

Access function
As a model of the concept RegularTriangulationCellBase_3, Regular_triangulation_cell_base_with_weighted_circumcenter_3 provides a weighted_circumcenter() member function. In this model, the weighted_circumcenter() member function returns the weighted circumcenter of the cell. This Point_3 is computed using the Construct_weighted_circumcenter_3 functor of the traits class when this function is first called and its value is stored. In the next calls, the cached value is returned. Note that the returned point has no weight.
const Point_3 &	weighted_circumcenter (const Traits &gt=Traits()) const
	Computes the weighted circumcenter of the tetrahedron, or retrieves it if it has already been computed.
void	swap (Regular_triangulation_cell_base_with_weighted_circumcenter_3 &other) noexcept
	Swaps the Regular_triangulation_cell_base_with_weighted_circumcenter_3 and other.
