   //! For all algorithms The resulting shape is composed of

   //! v = angle2) if the sphere is truncated in the v parametric
   //! direction (they may be cylindrical faces in some

   //! of torus, two planar faces to close the shape.(in the planes
   //! u = 0 and u = angle).
   //! Notes:
   //! -      The u parameter corresponds to a rotation angle around the Z axis.
   //! -      The circle whose radius is equal to the minor radius,
   //! located in the plane defined by the X axis and the Z axis,
   //! centered on the X axis, on its positive side, and positioned
   //! at a distance from the origin equal to the major radius, is
   //! the reference circle of the torus. The rotation around an
   //! axis parallel to the Y axis and passing through the center
   //! of the reference circle gives the v parameter on the
   //! reference circle. The X axis gives the origin of the v
   //! parameter. Near 0, as v increases, the Z coordinate increases
   //! (following the standard trigonometric convention: Z = r*sin(v)).
