OutputIterator
theta_extremal_points ( Circle_3<SphericalKernel> c,
Sphere_3<SphericalKernel> sphere,
OutputIterator res)
Copies in the output iterator the theta-extremal points of the circle relatively to sphere. res iterates on elements of type Circular_arc_point_3<SphericalKernel>, lexicographically sorted in the cylindrical coordinate system relative to sphere. See section 14.2 for definitions.
Precondition: c lies on sphere and is a normal circle.
