I refactored a bunch of the easing styles from Raphael.js to use with data structures (attached).  Look in [pd movers] and then [pd animate].

The patch itself only works in Pd-l2ork, but you can break out all of the animation logic.  You'll just need to replace any instance of [pi(--[pdinfo], with the value of Pi.  (I should probably get rid of that anyway.)

Here's a video:

Hi ,

I was wonderning if anyone of you had tried to implement easing in pd. I'm working on a video animation patch that uses "random" objects and the result would look much better if I could find a way to "smooth" the transitions. I already use the "line" object, but I'm looking for a way to slow down the line output when the line comes to its end, then start smoothly when it has a new target value. I'm thinking of using the expr object but I would be grateful if someone could give me some design hints on this...

Thank you very much,

D.S
