CGAL 4.12 - 2D and 3D Linear Geometry Kernel

## Definition

Refines:
AdaptableFunctor (with three arguments)
CGAL::compare_squared_radius()

## Operations

A model of this concept must provide:

Comparison_result operator() (const Kernel::Point_3 &p, const Kernel::FT &sr)
compares the squared radius of the sphere of radius 0 centered at p to sr. More...

Comparison_result operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::FT &sr)
compares the squared radius of the sphere defined by the points p and q to sr.

Comparison_result operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r, const Kernel::FT &sr)
compares the squared radius of the sphere defined by the points p, q, and r to sr.

Comparison_result operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r, const Kernel::Point_3 &s, const Kernel::FT &sr)
compares the squared radius of the sphere defined by the points p, q, r, and s to sr.

## ◆ operator()()

 Comparison_result Kernel::CompareSquaredRadius_3::operator() ( const Kernel::Point_3 & p, const Kernel::FT & sr )

compares the squared radius of the sphere of radius 0 centered at p to sr.

This returns the opposite sign of sr.
