## 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.

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.
