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

The mapping library is very likely to have stuff that would be helpful to you, I guess..

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.)

you can have a try with line3 from the nusmuk-utils lib. it's a line object using a 3rd order interpolation aiming to smooth transition... it really look at what you describe.

Those give you a smooth ramp between -1 and 1:
[3.1415, 0 3000( | [line 0 20] | [cos]
or:
[-3, 3 3000( | [line 0 20] | [expr tanh($f1)}
