## Definition

template<class Traits>
class CGAL::Barycentric_coordinates::Mean_value_2< Traits >

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 necessarily positive only inside the kernel of a star-shaped polygon and inside any quadrilateral.

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