[JAVA3D] setting appearance for a obj file

[Madeti, Henu S. (UMR-Student)]

Hi all,
I'm working on a code that would have to set the appearance for each part of obj file 
differently.
One way of doing it is divide the obj files into parts, set the appearance differently 
and load them.
but the problem here is with display size and location. I want them to be displayed as 
they are all from a single obj file, but it doesnt .
Does anyone know how to solve this tricky question?
thanks
