Ripples

Hello
I am trying to create ripples that are influenced by a number which I pass to the function via a database. I want to have four points that the ripples come from. I was wondering if there are any examples like that any one has done or any sugestions on where to start?

I tried implenting this algorithm, but I didn't have much luck. It's not a very complicated one, though.

hi jen,
I'm developing a (hopefully educational) radiation simulation for a physics course I'm associated with:
http://web.mit.edu/mdanzig/www/p5waves_2d_hi.html
Which uses a basic convolution algorithm (or "Finite Difference Time Domain" technique, if you want to be fancy) to simulate waves or ripples in a medium. Maybe this is useful to you?

ps. Sorry the code is a mess, but it's a work in progress  It's also probably not particularly optimized.
pps. Processing is great! I just discovered it a couple of weeks ago. Coming from Director it's a breath of fresh air.

this applet is really really good...
I kept struggling a week to do something like this, and you did a much better job... congratulations!
