CGAL 4.10 - 2D Generalized Barycentric Coordinates
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
 Traits must be a model of the concepts BarycentricTraits_2 and PolygonTraits_2.
Is Model Of:
BarycentricCoordinates_2
Precondition
The provided polygon is strictly convex.
Examples:
Barycentric_coordinates_2/Discrete_harmonic_coordinates_example.cpp.
