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...

Member Function Documentation

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.
