CGAL 5.4.4 - Weights
Barycentric Region Weight
#include <CGAL/Weights/barycentric_region_weights.h>


This weight is the area of the shaded region in the figure below. The region is formed by the two midpoints of the edges incident to q and the barycenter of the triangle [p, q, r].

Template Parameters
 GeomTraits a model of AnalyticWeightTraits_2 for 2D points; a model of AnalyticWeightTraits_3 for 3D points
