CGAL 5.5.1 - 2D Generalized Barycentric Coordinates
CGAL::Barycentric_coordinates::Wachspress_2< Traits > Class Template Reference

#include <CGAL/Barycentric_coordinates_2/Wachspress_2.h>

## Definition

The class Wachspress_2 implements 2D Wachspress coordinates ( [2], [8], [10] ).

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 it is better to use the class Triangle_coordinates_2. Wachspress coordinates can be computed exactly, and they are always positive in the closure of a strictly convex polygon.

Deprecated:
This part of the package is deprecated since the version 5.4 of CGAL.
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.
