#include <CGAL/global_functions_spherical_kernel_3.h>

Comparison_result	compare_theta ( Circular_arc_point_3<SphericalKernel> p, Circular_arc_point_3<SphericalKernel> q, Sphere_3<SphericalKernel> sphere)
		Compares the -coordinates of p and q relatively to sphere. Precondition:  p and q lie on sphere, but do not coincide with the poles of sphere.
Comparison_result	compare_theta ( SphericalKernel::Circular_arc_point_3 p, SphericalKernel::Vector_3 m, SphericalKernel::Sphere_3 sphere)
		Compares the -coordinates of p and of the meridian defined by m (see section 12.2) in the cylindrical coordinate system relative to sphere . Precondition:  p lies on sphere, but does not coincide with its poles. m ≠ (0,0,0) and the z-coordinate of m is 0.
Comparison_result	compare_theta ( SphericalKernel::Vector_3 m, SphericalKernel::Circular_arc_point_3 p)
		Same as previous, with opposite result.
