Functions

template<typename GeomTraits >
GeomTraits::FT CGAL::Weights::triangular_area (const typename GeomTraits::Point_2 &p, const typename GeomTraits::Point_2 &q, const typename GeomTraits::Point_2 &r, const GeomTraits &traits)
 computes the area of the triangular cell in 2D using the points p, q and r, given a traits class traits with geometric objects, predicates, and constructions.
 
template<typename GeomTraits >
GeomTraits::FT CGAL::Weights::triangular_area (const typename GeomTraits::Point_3 &p, const typename GeomTraits::Point_3 &q, const typename GeomTraits::Point_3 &r, const GeomTraits &traits)
 computes the area of the triangular cell in 3D using the points p, q and r, given a traits class traits with geometric objects, predicates, and constructions.
 
template<typename K >
K::FT CGAL::Weights::triangular_area (const CGAL::Point_2< K > &p, const CGAL::Point_2< K > &q, const CGAL::Point_2< K > &r)
 computes the area of the triangular cell in 2D using the points p, q and r which are parameterized by a Kernel K.
 
template<typename K >
K::FT CGAL::Weights::triangular_area (const CGAL::Point_3< K > &p, const CGAL::Point_3< K > &q, const CGAL::Point_3< K > &r)
