Create a torus centered about the origin and with the z-axis pointing up through the ring. The surface 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 number of polygons that will be created radially around the ring and tuberes is the number of polygons 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. Optional, WORLD is the default.
An object handle that references the new object is returned.
