I tried to google on this, but didn''t turn up anything useful, so here goes... I need to create various length toroidal triangle strips (formed from spheres) and have them all be oriented differently. Although they are essentially the same triangle strip (the sphere radius is static), the length of the strip and the orientation of it change from call to call. Is there a way to create a couple display-lists to handle all this for me? The biggest problem I''m having is getting the strip to come out with the proper length. Thanks in advance
