I normally use Shape3D's to pick on. Picking of course works by
starting on a Shape3D that you have selected, and then if you want a
TransformGroup, it finds the next TransformGroup in the hierarchy with
pick reporting enabled (if I'm not mistaken). Therefore, I normally
just ask for Shape3D "picks" and do the setUserData on the Shape3D.

hi Kyle,
thats exactly what i tried to do, but my problem is so that after
clicking i
only retrieve a TG and when i apply getUserData() on this TG it gives
null,
but when i print this TG it gives a certain code which is different for
every object but also different than when they were created. so there is
no
value which really stays constant and can be matched with. Dont know why
..
