Sorry to interpose but what you'll do if the squashed object exceed the
bounds of the other object, which will certainly often occurs? You must
remove parts from the copy to make sure we don't have floating shadows.
Second thing, why do you say scaling on y, shouldn't this depends on the
light position and then, you must flatten your object from this point of
view? I think itsn't too simple to have shadows in j3d (except maybe in a
particular scene which isn't too useful) but if someone has do it, I'm
really interested!
