However, creating accel/decel with the key frames is fairly trivial. It requires a little math, but with the spline interpolation, not many key frames are needed (you just have to watch for overshoot). It would be real nice if Lightwave graphed out distance, velocity, acceleration, angle, etc. over time and allowed interactive modification of that graph. I'll mention this to Allen. %~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~% % ` ' Mark Thompson CONCURRENT COMPUTER % % --==* RADIANT *==-- mark@westford.ccur.com Principal Graphics % % ' Image ` ...!uunet!masscomp!mark Hardware Architect % % Productions (508)392-2480 (603)424-1829 & General Nuisance % % % ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
