SphericalKernel::CompareTheta_3

An object fo of this type must provide:

Comparison_result	fo ( SphericalKernel::Circular_arc_point_3 p , SphericalKernel::Circular_arc_point_3 q )
		Compares the -coordinates of p and q in the cylindrical coordinate system relative to the context sphere used by the function SphericalKernel::compare_theta_3_object. Precondition:  p and q lie on the context sphere used by the function SphericalKernel::compare_theta_3_object, but do not coincide with its poles.
Comparison_result	fo ( SphericalKernel::Circular_arc_point_3 p , SphericalKernel::Vector_3 m )
		Compares the -coordinates of p and of the meridian defined by m (see section 14.2) in the cylindrical coordinate system relative to the context sphere used by the function SphericalKernel::compare_theta_3_object. Precondition:  p lies on the context sphere used by the function SphericalKernel::compare_theta_3_object, but does not coincide with its poles. m ≠ (0,0,0) and the z-coordinate of m is 0.
Comparison_result	fo ( SphericalKernel::Vector_3 m , SphericalKernel::Circular_arc_point_3 p )
		Same as previous, with opposite result.
Comparison_result	fo ( SphericalKernel::Vector_3 m1 , SphericalKernel::Vector_3 m2 )
		Compares the -coordinates of the meridians defined by m1 and by m2 (see section 14.2) in the cylindrical coordinate system relative to the context sphere used by the function SphericalKernel::compare_theta_3_object. m1 ≠ (0,0,0), m2 ≠ (0,0,0) and the z-coordinate of m1 and m2 is 0.
