Operations

A model of this concept must provide:

Oriented_side operator() (const Kernel::Weighted_point_2 &p, const Kernel::Weighted_point_2 &q, const Kernel::Weighted_point_2 &r, const Kernel::Weighted_point_2 &s)
 returns the relative position of point s to the oriented power circle defined by p, q, and r. More...

◆ operator()()

Oriented_side Kernel::PowerSideOfOrientedPowerCircle_2::operator() ( const Kernel::Weighted_point_2 p,
const Kernel::Weighted_point_2 q,
const Kernel::Weighted_point_2 r,
const Kernel::Weighted_point_2 s 
)

returns the relative position of point s to the oriented power circle defined by p, q, and r.

The order of the points p, q and r is important, since it determines the orientation of the implicitly constructed power circle.

Precondition
the bare points corresponding to p, q, r are not collinear.
