I have been playing some more and I did a little test program that illustrates one way of moving the camera around to different places in the scene graph and keeping both the behavior associated with moving it and the overlays. It is not possible, to the best of my knowledge, to use the ViewingPlatform class (and thus the OrbitBehavior) and be able to move the camera in the scene graph without losing access to the behavior. When you call ViewingPlatform.setViewPlatform() the ViewPlatform does change but the TransformGroup that OrbitBehavior is operating on stays attached to the original position. This program does not use multiple ViewPlatforms, rather it detaches and reattaches a BranchGroup to move both the TransformGroup and the ViewPlatform. Instead of the OrbitBehavior it is using the NavigationHandler class from the j3d cvs which has the advantage of being animated. The program is on the web at: http://odin.himinbi.org/j3d-overlay/#view-platform-test There is an initial setup screen. The scene is a set of spheres that spiral around in a sphere, changing hue as they go around and brightness as they descend. Settings like the number of spheres, the number of camera mounts and colors can be changed. As well as illustrating the NavigationHandler it also shows how to do overlays with more than one color and font style using the AttributedText class. There is no error checking on the fields where you enter numbers so entering things that aren't numbers will cause it to crash.
