(sorry I can't speek english very well)

It's very easy, Java3D already have what you need. Take a look at
MouseTranslate in the javadoc.

All you have to write is something like that :
MouseBehavior mouseTranslate = new MouseTranslate(this.mouseTransform);
this.mouseTransform.addChild(mouseTranslate);
mouseTranslate.setSchedulingBounds(schedulingBounds);

Don't forget to put the visual objects you want to move while your
mouse drag in the TransformGroup "mouseTranslate".

I hope my explanations are clear enough for you to understand :)

Take a look at the other MouseBehaviors : MouseRotate and MouseZoom,
they are also interresting. Do not use MouseZoom when you work with
parrallel projection.

HI,

I'm very glad that someone has responded.

Unfortunately MouseTranslate behavior is not what I had in mid. I have
tried with it in first place.

When the button is pressed over visual object and mouse is dragged the
selected object follows mouse movements and that is OK.
But I also want that during the drag, object lies under mouse cursor -
so that it seems that i have grabbed a point on that object and that
point acts like a handle for moving.

thanks
