Hi,
I recognize your problem, I just struggled with something similiar when
trying to center a Shape3D object on the screen.
My problem was that I was using the wrong bounds for my object, causing the
eye distance to become much to large. So your problem could be that you use
the sceneBounds of the applet, not the object itself.
The following code may be used to find the bounds of any object derived
from Node:
System.out.println("Is bounds auto computed = " +
nodeObject.getBoundsAutoCompute());
System.out.println("bounds = " + nodeObject.getBounds());
Hope this is of any help.
