Hi Josh,
I have code which does about what you are looking for. However, I did not
yet test
the part which translates the center of rotation away from the origin (it is
from an old
test project that got abandoned). The code is based somewhat on sourcecode
from
the sun utilities. You can find t

The internal guts, from what I understood of Java3D is OpenGL. For more info
on OpenGL take a look at the www.opengl.org web site. All you want to know
about it is there.

Look at my page again with regards to the mouse behaviors. I did

If you compare each of my mouse behaviors with sun's original, you will
see that it is just a matter of changing the "!" in front of
the
your solution "1".
You can also check out my modified behaviors at:

Instead of telling it the viewers position, you could pass some other 3D
