       SippTorus bigradius smallradius radialres tuberes shaderhandle [texture]
              Create  a  torus centered about the origin and with
              the z-axis pointing up through the ring.  The  sur-
              face  is  shaded  with  the  algorithm  and surface
              parameters specified by shaderhandle.  bigradius is
              the  radius  of  the  ring  and  smallradius is the
              radius of the "tube" itself.  radialres is the num-
              ber  of  polygons  that  will  be  created radially
              around the ring and tuberes is the number of  poly-
              gons that will be created around the tube.

              Texture is the texture mapping algorithm to use for
              the object.  The NATURAL texture mapping is  a  two
              dimensional  mapping  with  the  x coordinate going
              around the small circle and the y coordinate  going
              around the large circle.

              See   the   help  file  sipp/Texture-Map  for  more
              details.

              An object handle that references the new object  is
              returned.
