CGAL 5.3.1 - 3D Triangulations
CGAL::Triangulation_simplex_3< Triangulation_3 > Class Template Reference

#include <CGAL/Triangulation_simplex_3.h>


The class Triangulation_simplex_3 stores a simplex of any dimension defined by the Triangulation_3 class.

It also defines the operator less such that simplices can be stored in a map or a set of simplices. The simplex is invalidated by any change in the triangulation.


It is parameterized by the triangulation it derives the simplices from.

◆ operator Cell_handle()

template<typename Triangulation_3 >
CGAL::Triangulation_simplex_3< Triangulation_3 >::operator Cell_handle ( ) const

Returns the Cell_handle stored in the simplex.

dimension() == 3

◆ operator Edge()

template<typename Triangulation_3 >
CGAL::Triangulation_simplex_3< Triangulation_3 >::operator Edge ( ) const

Returns the Edge stored in the simplex.

dimension() == 1

◆ operator Facet()

template<typename Triangulation_3 >
CGAL::Triangulation_simplex_3< Triangulation_3 >::operator Facet ( ) const

Returns the Facet stored in the simplex.

dimension() == 2

◆ operator Vertex_handle()

template<typename Triangulation_3 >
CGAL::Triangulation_simplex_3< Triangulation_3 >::operator Vertex_handle ( ) const

Returns the Vertex_handle stored in the simplex.

dimension() == 0

◆ operator
template<typename Triangulation_3 >
bool CGAL::Triangulation_simplex_3< Triangulation_3 >::operator< ( const Triangulation_simplex_3< Triangulation_3 > &  s1)

Defines a ordering on the simplices.

This ordering depends on the memory layout and is independent of the geometry. Therefore, the ordering is not intrinsic
