Yes the same java program should be able to run with both versions of the Java3D library without recompiling. More below....

If my udnerstanding is correct, Java 3D uses native calls (directx, etc) so if you compiled under win32 using libraries written for windows 3d graphics, you will very distinctly have ap roblem on an SGI/unix box. You will need to bring the code over and compile it on the SGI/unix box with the proper environemt.

Compiling a java program does not 'package' the native libraries into the program, so if all she did was to bring the compiled .class (or .jar) files over to the SGI machine, then they should work.
This assumes (as you said) that the SGI machine has a working Java runtime environment, and that it has the (both java and native) SGI Java3D libraries installed.
If you don't have any 'Native code' in your program (are you using JNI?) then the most likely cause for the 'Segmentation Violation' is that the way you are using Java3D you have aggravated a bug in the SGI version of Java3D. I'm not upto date on what the latest version of J3D is that is available on the SGI platform, but it's also possible that the one you are using on the SGI side is older than the J3D libraries oyu compiled with on the Windows side. (Same could be true for the JVM.)
If you are using Native code, then the most likely place for this problem would be in your native code. You would *have* to recompile the native portion of your code on the SGI no matter what.
I would start first by making sure you're using the same versions to do you compile as you do to run it. (You could do this by compiling on the SGI side, if you have the JDK there?) If you still have problems I think you'll have to talk with someone at SGI about their implementations of Java, and Java 3D.
