Instead of scaling the scene i would use View.setFieldOfView( ) for perspective
Projection or View.setScreenScale( ) and setScreenScalePolicy( View .
SCALE_EXPLICIT ); for orthogonal projection. Add this method calls for example
to a ChangeListener of a JSlider or use any other GUI element you like (e.g +,
- button: by pressing + you zoom in with a predefined stepwidth by pressing -
you zoom out).
