I just want to thank you for your answer, I guess the get-technik is a try to reduce the garbage collector work. Once again - thanx.

To have a get-method, which is not returning a > value? The method requires you to pass a transform in and the values will be set into that transform. This is an optimization that allows you to create a single transform and use it to fetch values from all over the place without each method having to create a new object and return it. > 3.)

Say, this is throwing an exception: > vpTrans = su.getViewingPlatform().getViewPlatformTransform(); > vpTrans.setCapability(TransformGroup.ALLOW_TRANSFORM_READ); You will want to work with the transform group above the view platform. You can get access to this in ViewingPlatform.getMultiTransformGroup() if you are using simple universe, but you can also construct your own universe and just keep a reference to the transform that you use on the view side of the scene graph. To find the position of the view platform, you should be able to get the transform and apply it to a point that started at 0,0,0.
