CGAL 5.4.5 - Weights
Mixed Voronoi Region Weight

#include <CGAL/Weights/mixed_voronoi_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 circumcenter of the triangle [p, q, r].

However, unlike the original Voronoi Region Weight, if one of the angles in the triangle [p, q, r] is obtuse and the circumcenter vertex of the region is outside this triangle, this vertex is moved to the midpoint of the edge [r, p] as shown in the figure below.
