Wiz (he is smart!) asks: "I do not understand. NURBs are just one class of splines, Non Uniform Rational B-splines, with some interesting math to let them approach quadratics more accuratly. So a NURBs modeller is a spline modeller. What sort of splines does Hash use?" Oh, God... don't ask me that, please... :-> Seriously, my understanding was that AM uses some other kind of splines, but if there's only one kind of splines, then I guess it doesn't... or something. Don't know much about splines. I've only used the demo version of Animation Master and the beta version of Rhino, and with both of them I found myself bested very quickly. Very, very quickly. I like Amorphium, though. -Nemo (I think I'll have myself a little lie-down now)
