CGAL 5.1.2 - 2D Generalized Barycentric Coordinates
|
#include <CGAL/Barycentric_coordinates_2/Wachspress_2.h>
The class Wachspress_2
implements 2D Wachspress coordinates ( [2], [6], [9] ).
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.
