Michael,
In my opinion the com.sun. classes are VITAL. I think what Sun is
pointing out is that because these are not an official part of Java 3D
they may change on a whim, thus you can't count on them remaining the
same from one release to the next (I've never noticed a change).
Sun - please clarify if I'm wrong but we are encouraged to legally use
the source to these for our own purposes.
Sun - I would encourage some of these being moved into the official Java
3D. Simple Universe and Picking are the foundation to many applications
- if they were to change we'd have a potential nightmare on our hands.
