Hi,
I just upgraded to Java3D 1.3. The programs compiles fine.
In my application I am mixing 3D-objects created with Java3D and
3D-objects created with VisAD. The VisAD-created object are not longer
displayed in my 3D view.
I am attaching the code, creating the VisAD-object.
Any ideas?
Thanks, Desiree
