[JAVA3D] Problems to load a 3DS object (test source valid)

[Fredrik Andersson]

Hello!

I Try to load a 3DS-object but the object will not be visible at all.

I'm not so good at 3D-studio so I downloaded a object from the Internet so a
have something to test with.

That object can be found at:
http://medlem.spray.se/fredand44/questions/girl.3DS
I also have an other one that I have developed my self at:
http://medlem.spray.se/fredand44/questions/test.3DS
But my own object doesn't seems to have any Shape3Ds?

I use the Import3DS
from:http://www.j3d.org/utilities/loaders/3ds/mulder.html
to load my objects. So if you would like to test this I think you have to
download it.

So if any one could give me a hint I would be most thankfull!

Best regards
Fredrik Andersson

My code to test this is:
