2D Generalized Barycentric Coordinates 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.

Template Parameters
Traitsmust be a model of the concept BarycentricTraits_2.
Is Model Of:
BarycentricCoordinates_2
Examples:
Barycentric_coordinates_2/Mean_value_coordinates_example.cpp, and Barycentric_coordinates_2/Terrain_height_modeling.cpp.
