Kernel::ComputeSquaredRadius_2 Concept Reference

Definition

Operations

A model of this concept must provide:

Kernel::FT operator() (const Kernel::Circle_2 &c)
 returns the squared radius of c.
 
Kernel::FT operator() (const Kernel::Point_2 &p, const Kernel::Point_2 &q, const Kernel::Point_2 &r)
 returns the squared radius of the circle passing through p, q and r. More...
 
Kernel::FT operator() (const Kernel::Point_2 &p, const Kernel::Point_2 &q)
 returns the squared radius of the smallest circle passing through p, and q, i.e. one fourth of the squared distance between p and q.
 
Kernel::FT operator() (const Kernel::Point_2 &p)
 returns the squared radius of the smallest circle passing through p, i.e. \( 0\).

◆ operator()()

Kernel::FT Kernel::ComputeSquaredRadius_2::operator() ( const Kernel::Point_2 p,
const Kernel::Point_2 q,
const Kernel::Point_2 r 
)

returns the squared radius of the circle passing through p, q and r.

Precondition
p, q and r are not collinear.
