  //! For all algorithms The resulting shape is composed of
  //! -      a lateral toroidal face,
  //! -      two conical faces (defined  by the equation v = angle1 and
  //! v = angle2) if the sphere is truncated in the v parametric
  //! direction (they may be cylindrical faces in some
  //! particular conditions), and in case of a portion
  //! 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 decreases.
