The OrbitBehavior does take into account any translation changes to the
view Transform, the view will be positioned at the translated point
but will always point to the rotation center.
Java 3D Fly Through uses this functionality for the 'Show All' command.
How does this differ from your requirements ?
As a side note, the resetViewPosition method should not be made public as that
would require user code to have knowledge about which ViewPlatformBehavior
is currently driving the view.
