You're going to want to spend a bit of time looking through the docs and examples. Java3D is non trivial.
The basic structure you're looking for is:
SimpleUniverse
{
BranchGroup
{
Light {}
TransformGroup {
Shape3D (shoulderShape)
TransformGroup {
Shape3D (elbowShape)
TransformGroup
{
Shape3D (wristShape)
}
}
}
}
}Go to the directory where you installed Java, and look for the directory with the Java3D examples. Open the index page in your web browser (on my system this is C:\j2sdk1.4.2_04\demo\java3d\index.html). Play with the examples and look at the source code to see how they work.
You may also want to look at http://java.sun.com/developer/onlineTraining/java3d/j3d_tutorial_ch2.pdf
