Hello!
Sorry to bother you again about this.
I have build a 3D-object with a couple of Shape3D objects, add them to a
TransformGroup. Now its time for the texture to the different
Shape3D-surfaces. So I guess that I have to start to set the cordinates for
the Texture before I chane my Appearance. I guess that the texturecordinets
should be the same as the cordinates for the Shape3D, correct me if I'm
wrong.
But I end upp with this Exception:
Exception in thread "main" java.lang.IllegalStateException: GeometryArray:
mu

Below is my 2 classes to test this. The MTLB Class is the Shape3D and the
other one is just for viewing any Shape3D. You can turn the loaded Shape3D
around with the arrow keys.
So if any one could explain why I get the Exception it would be great.
Perhaps you could give some more hints to solve this if you see any thing
strange.
Best regards
Fredrik
