Re: [PD] acceleration - deceleration between coordinates - how to do this?

[cyrille henry]

hello,

i prefer using the line3 object for this.

hi,

a very common approach to this is using a function like cosine or an other function which fits your needs. u can still use the vline but instead of directly using it use its output to control the "fade function":

[line]
|
[* 3.14159]
|
[cos]

here's a page with a few useful examples of other functions:

Hi guys,

I'm working on a patch (rjdj scene) where I'm moving a little object around on a plane. The object is been given random coordinates which it is supposed to gradually move to in five seconds.

Right now my solution is to bang the x- and y-coordinates into a line-object which works fine, but I'd prefer for the movement to be more "natural". By natural I mean that the object accelerates in the beginning and then decellerates near the end until it comes to a full stop at the exact coordinates that where randomly produced..

I've been trying to get my head around a solution for quite a while now, but unfortunately no luck so far.

I'm sure this must be simple stuff for some of you PD-geniuses out there, and I'm hoping that one of you will stand up and show me how it's done :)

Thanks in advance,
Thomas :)
