I have an application where I have multiple ViewPlatforms that I move between. I have been using the ViewingPlatform class to handle the ViewPlatform because it lets me use the OrbitBehavior and I like the behavior. Also I am using the overlay library that I just posted about and the overlays are just textures right in front of the camera (attached to the ViewPlatformTransform.) The problem that I am having is if I use viewingPlatform.setViewPlatform it does change the attached ViewPlatform but the ViewPlatformTransform stays attached to the default position. This is a problem because A, I no longer have the orbit behavior to change my position and B, it leaves the overlays suspended in space. The obvious solution is to move the whole thing, but the scene graph for the ViewingPlatform is compiled when the object is created so I can't do something like: SimpleUniverse universe = new SimpleUniverse(canvas); ViewingPlatform viewingPlatform = universe.getViewingPlatform(); TransformGroup viewTransform = viewingPlatform.getViewPlatformTransform(); BranchGroup cameraBase = (BranchGroup)viewTransform.getParent(); cameraBase.setCapability(BranchGroup.ALLOW_DETACH); I get an exception thrown trying to access the parent of a compiled graph. Is there any way to both use the OrbitBehavior and to be able to change the group that the ViewPlatform is a child of (or to use multiple ViewPlatforms?)
