David, Vector mathematics. Well, that reminds me of my electrical engineering days. I will check out the books. I am waiding through the exercises in the 3DS book. I already know basic a little, so I can write scripts to move objects. But generating particles? I assume that one of the IPAS programs is better than others. Do you have a favorite? I find Vapor hard to control, even though it has lots of settings. Any ideas about how a script would call and execute AXP's? (like explode on impact) Sanford
