hi marabou,

hey!  thats one i can answer!  difference is a constructive
solid geometry option, and that only works with "primitive"
shapes, such as cylinders, boxes, spheres, etc.  all of those
shapes except the donut (toroid) are listed in the scene
language help document in section 2.2.

good luck, miker
