CGAL::compare_theta_z

#include <CGAL/global_functions_spherical_kernel_3.h>

bool
compare_theta_z ( Circular_arc_point_3<SphericalKernel> p,
Circular_arc_point_3<SphericalKernel> q,
Sphere_3<SphericalKernel> sphere)
Compares p and q according to the lexicographic ordering on theta and z-coordinates in the cylindrical coordinate system relative to sphere.
Precondition: p and q lie on sphere, but do not coincide with the poles of sphere.
