Operations
As in the Kernel concept, for each of the function objects above, there must exist a member function that requires no arguments and returns an instance of that function object. The name of the member function is the uncapitalized name of the type returned with the suffix _object appended. For example, for the function object SphericalKernel::Construct_circular_arc_3 the following member function must exist:
Construct_circular_arc_3	construct_circular_arc_3_object () const

Operations on a given sphere,
A context sphere must be provided to the following functions:
Compare_theta_3	compare_theta_3_object (const Sphere_3 &sphere) const
Compare_theta_z_3	compare_theta_z_3_object (const Sphere_3 &sphere) const
Compare_z_at_theta_3	compare_z_at_theta_3_object (const Sphere_3 &sphere) const
Compare_z_to_right_3	compare_z_to_right_3_object (const Sphere_3 &sphere) const
Make_theta_monotone_3	make_theta_monotone_3_object (const Sphere_3 &sphere) const
