Oh for cryin out loud DUDE it is not something you should be asking. Get a tutorial at java.sun.com and then come back and ask questions. What you are asking is a basic and I mean basic building block of any scene in j3d.

If you still don't understand or have problems come back here and post more specific questions.

(Yes, this is sort of a clueless-newbie question but it IS J3D specific so I personally don't fault him for posting it here.)
