Hi all!
I am trying to draw an objet over a given plane, and I don't want the
object to be drawn outside the limits of the plane. In opengl this can be
achieved by drawing the plane (floor) and at the same time writing a
certain value to the stencil buffer. Then, in the draw routine, the
object will be drawn only over the pixels with that a certain value.

I don't know the way to do this in Performer, so any help would be
appreciated.
