The mousebehavior callbacks are like feedback loops to the program that
allow you to know which transformgroup was acted upon by whichever
mousebehavior generated the callback.
If you look through the examples of mouse behaviors, I believe that there
is an example that does what you propose. One

ccurs when the mouse pointer is on an object for a

sorry, i need to clarify one thing.
I haven't been actively doing any Java3D and forgot that the callback
method is implemented in the picking versions of those three
behaviors. So what I was talking about would require using the
extended picking versions of those three behaviors.
The Sun example
Each of the three behaviors you mentioned has a callback method which
when setup returns the transformgroup of the object that was zoomed,
translated, or rotated.
From this transformgroup, you can get the Transform3D and hence the
three coordinates.
If you want to simply get the three coordinates

This is actually very simple.
Suppose you already know the TransformGroup for an object you want to
rotate to a specific angle around the X axis. Lets call this Object
TransformGroup JohnTG.
Transform3D tempT3D = new Transform3D();
(JohnTG).getTransform(tempT3D);

The terminology rotate seems to always confuse people.
If you rotate an object, or a group of objects, it should rotate the object
around the upper most point in the hierarchy of the Transform group where
you have the behavior acting upon.
In your case if TG1 is at 0,0,0 and you rotate, then eve
n is how I can put MouseRotate in the left button
and MouseTranslate in the right button.
Thanks.
PD Eric your behaviors are very
good.Thanks
