compare_y_to_right()

CGAL::Comparison_result CGAL::compare_y_to_right	(	const Circular_arc_2< CircularKernel > &	ca1,
		const Circular_arc_2< CircularKernel > &	ca2,
		Circular_arc_point_2< CircularKernel > &	p
	)

#include <CGAL/global_functions_circular_kernel_2.h>

Compares vertically the two arcs, to the right of the point p,.

Precondition

p is an intersection point of the arcs, and the arcs are defined to the right of p.

x_extremal_points()

template<class OutputIterator >

OutputIterator CGAL::x_extremal_points	(	const Circle_2< CircularKernel > &	c,
		OutputIterator	res
	)

#include <CGAL/global_functions_circular_kernel_2.h>

Copies in the output iterator the x-extremal points of the circle.

res iterates on elements of type Circular_arc_point_2<CircularKernel>, sorted in x.

y_extremal_points()

template<class OutputIterator >

OutputIterator CGAL::y_extremal_points	(	const Circle_2< CircularKernel > &	c,
		OutputIterator	res
	)

#include <CGAL/global_functions_circular_kernel_2.h>

Copies in the output iterator the y-extremal points of the circle.

res iterates on elements of type Circular_arc_point_2<CircularKernel>, sorted in y.
