I'm having trouble mapping an image to a torus. The patter seems to be mirrored
above and below the torus's "equator". Is there a way to get this to stop?

-Mike

torus
{
 #local Width = 64;
 #local Height = 64;
 #local Radius = Width/2/acos(pi/4);
 Width, Radius
// clipped_by {cylinder {0,y*Height,Width}}
 texture
 {
  pigment
  {
   image_map {png "texture_bowels_test.png"}
   warp
   {
    toroidal
    orientation y
    dist_exp 0
    major_radius Width
   }

  }
  scale Width
 }
 translate y*Height/2
 translate Left_Vector*+1/2
}
