Hey everyone!

I've been sort of playing around with animation here lately with some simple objects. One of them is a ball. Now pretty much every animator will study a bouncing ball and perfect it's bounce! I'm doing this without any training, and by that I mean I'm just studying a ball bouncing and trying to replicate it's bounce. I don't have a school telling me to do this, I just wanted to do it. So my resources have mainly just been my previous knowledge of how to do key frame animation and that's about it. Anyways.... I just want some critique on these two animations. I know, the second one is really short so if you don't want to give me any feedback on that one -- it's fine. I would really like some critique on the first one though. It took me about a day to complete. I can't put my thumb on it, but there just seems to be something off about it. Perhaps it's the abrupt stop of bounces??

Regarding the first link:

- My biggest crit is that the spacing is very even across all of the bounces. You should be easing out of the peaks and subsequently easing into them as the ball comes off the ground.

dirty sketch for spacing:

- The timing also feels very sluggish. Try speeding it up across the board. Right now it feels like a ball bouncing on the moon.

- The height of the ball is also wrong from one bounce to the next. A bouncing ball is very mathematical.

dirty sketch for y-axis falloff: straight line through each crescendo.

@stuartb, thanks for those sketches... Let me see what I can work up with that in mind!
