If you are already into the Advanced Motion Lab, then you >are accelerating at a rapid pace. The AML is unexplored >territory for me. I hope you continue to have progress. Perhaps in too many directions at once? Rather than accelerating, I think I am more sort of cannoning around, emulating the very bounce I tried to create. I really did just want this to animate Rhino stuff, and got carried away. Try the AML! I looked at it in complete loss at first. But in the end....at its simplest....you pick an object, which flicks up its attributes. Pick an attribute (position), which shows a line on the "screen". Pick a place in the curve, wait for the "pencil" to show onscreen. Create a dot. You can literally drag the dot to make what was linear motion/time into something that follows the curve you draw. You can add points at any place on the line, and create motion/time of any sort. If the line is vertical, you have instant motion. Horiz makes it stand still. And what have you in between. You still need keyframes as you do in the normal screen. So far I have only done position, to accelerate. I have to admit I have not even started on Origin etc etc. My chaotic progress has to have some linearity!
