Kernel::ComputeSquaredRadius_2

A model for this must provide:

Kernel::FT

fo.operator() ( Kernel::Circle_2 c)

returns the squared radius of

Kernel::FT

fo.operator() ( Kernel::Point_2 p, Kernel::Point_2 q, Kernel::Point_2 r)

returns the squared radius of the circle passing through

q and

Precondition:

p, q and r are not collinear.

Kernel::FT

fo.operator() ( Kernel::Point_2 p, 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
