This algorithm converts a bounded Sphere into a rational
B-spline surface. The sphere is a Sphere from package gp.
The parametrization of the sphere is
P (U, V) = Loc + Radius * Sin(V) * Zdir +
Radius * Cos(V) * (Cos(U)*Xdir + Sin(U)*Ydir)
where Loc is the center of the sphere Xdir, Ydir and Zdir are the
normalized directions of the local cartesian coordinate system of
the sphere. The parametrization range is U [0, 2PI] and
V [-PI/2, PI/2].
