Before my question, when I modified the scale of the transform in
ViewingPlatform, it didn't change the apparent size, but it did _allow_ the
apparent size to be increased via navigation. It was as if the apparent size
had been increased, but the apparent distance of the viewer from the scene
had also been increased, so that exactly the same portion of the view was
shown before and after.
I changed the scale in a subclass of ViewingPlatform via:
Transform3D transform = new Transform3D();
this.getViewPlatformTransform().getTransform( transform );
transform.setScale( transform.getScale() * (1 / factor) );
Have I changed the scale incorrectly?
