CGAL::z_extremal_points

#include <CGAL/global_functions_spherical_kernel_3.h>

template < class OutputIterator >
OutputIterator z_extremal_points ( Sphere_3<SphericalKernel> c, OutputIterator res)
Copies in the output iterator the z-extremal points of the sphere. res iterates on elements of type Circular_arc_point_3<SphericalKernel>, lexicographically sorted.

template < class OutputIterator >
OutputIterator z_extremal_points ( Circle_3<SphericalKernel> c, OutputIterator res)
Copies in the output iterator the z-extremal points of the circle. res iterates on elements of type Circular_arc_point_3<SphericalKernel>, lexicographically sorted.
Precondition: The circle is not contained in a plane orthogonal to the z-axis.
