Definition

template<class Traits>
class CGAL::Barycentric_coordinates::Wachspress_2< Traits >

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.
