CGAL 5.5.2 - Weights

#include <CGAL/Weights/inverse_distance_weights.h>

This weight is computed as \(w = \frac{1}{d}\) with notations shown in the figure below.

Here, the distance is computed between the points p and q.

Alternative formulations are explained in Implementation.

Alternative Formulations
This weight is a special case of the Shepard Weight.

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