how do I make vector graphics?

 XTrace is a program that support vector graphics but i don't know if it will be enough to create graphics like in another world. I think they used the motion-capture technique to create realistic movements.
 Another option is to use a conventional painting-animation program like deluxe paint and then use a bitmap to vector converter. You will find one or two in Aminet.

Hey, i just remembered of FantaVision! I believe that it should be a good choice for what you want to do. It's a very old program, though and it may not run at all on a newer Amiga.
