[JAVA3D] Problems with 3DS objects (test code valid)

[Fredrik Andersson]

Hello!

I can't get this right. I try to load a object from a 3DS-file but it will
not be visible in the Canvas. I do not know what I'm doing wrong. Perhaps my
3DS-files is corrupt, but I do not think so. I have also added lights.
So if any one could give me some code that loads and show a 3DS-object I
would be most thankfull.

My objects can be found at:
http://medlem.spray.se/fredand44/questions/girl.3DS
or
http://medlem.spray.se/fredand44/questions/test.3DS

The last one (test.3DS) doesn't seem to remain any Shape3D-objects
strangely.

So if any one could help me to load and add an 3DS-object, it would really
make my day!

PS I use starfire for loading the 3DS-file and I have looked at the
CargadorBob.java but it doesn't help. So I think some code really should
help.

Best regards
Fredrik
