CGAL::Euclidean_distance_sphere_point< Traits > Class Template Reference

#include <CGAL/Euclidean_distance_sphere_point.h>

Definition

The class Euclidean_distance_sphere_point provides an implementation of the GeneralDistance concept for the Euclidean distance ( \( l_2\) metric) between a \( d\)-dimensional sphere and a point, and the Euclidean distance between a \( d\)-dimensional sphere and a \( d\)-dimensional iso-rectangle defined as a \(k\)- \(d\) tree rectangle.

Parameters

Expects for the template argument a model of the concept SearchTraits, for example Simple_cartesian_d<double>.
