`#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.

Template Parameters

  Traits | must be a model of the concept `SearchTraits`, for example `Simple_cartesian_d<double>`.

Is Model Of:
  `GeneralDistance`

## Creation

| Euclidean_distance_sphere_point (Traits t=Traits())
| Default constructor.

## Operations

NT | transformed_distance (Query_item s, Point_d p) const
| Returns the distance between `s` and `p`.
NT | min_distance_to_rectangle (Query_item s, Kd_tree_rectangle< FT, D > r) const
| Returns the minimal distance between a point from the sphere `s` and a point from `r`.
NT | max_distance_to_rectangle (Query_item s, Kd_tree_rectangle< FT, D > r) const
| Returns the maximal distance between the sphere `s` and a point from `r` furthest to `s`.
NT | transformed_distance (NT d) const
| Returns \( d^2\).
NT | inverse_of_transformed_distance (NT d) const
| Returns \( d^{1/2}\).
