CGAL::Barycentric_coordinates::Discrete_harmonic_2< Traits > Class Template Reference

#include <CGAL/Barycentric_coordinates_2/Discrete_harmonic_2.h>

Definition

The class Discrete_harmonic_2 implements 2D discrete harmonic coordinates ( [2], [8], [1] ).

This class is parameterized by a traits class Traits, and it is used as a coordinate class to complete the class Generalized_barycentric_coordinates_2. For a polygon with three vertices (triangle) it is better to use the class Triangle_coordinates_2. Discrete harmonic coordinates can be computed exactly. By definition, they do not necesserily give positive values.

Template Parameters
