CGAL 5.1.3 - 2D Generalized Barycentric Coordinates
CGAL::Barycentric_coordinates::Mean_value_2< Traits > Class Template Reference

#include <CGAL/Barycentric_coordinates_2/Mean_value_2.h>

Definition

The class Mean_value_2 implements 2D mean value coordinates ( [5], [2], [3] ).

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. Mean value coordinates can be computed only approximately due to an inevitable square root operation, and they are necesserily positive only inside the kernel of a star-shaped polygon and inside any quadrilateral.
