Hi Christian,
Try:
java -Dj3d.g2ddrawpixel=false yourprogram
under OGL version or try DirectX version of
Java3D which should not have this background
performance problem.
Thanks.

>I set up a somewhat nice-looking solar-system so far. There are spinning

>(starfield) to the background that would move as the mouse would change the

>Has this something to do with the size of the texture? I mean the amount of

>I used pretty exactly the implementation of the API-example that is schowing
>the use of that feature...

>Am I missing something? Or is there another way to implement what I wanted?
