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 
)

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.

#include <CGAL/global_functions_circular_kernel_2.h>

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

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.

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

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.
