Jitter Balls

June 19, 2010 | 9:26 pm

Hey everyone, I have been looking for a few ways to create a jitter object that uses numbers to scale different balls or spheres – I have looked at the boidroids example and thats close put i was looking for something more like balls. Something that it a max/jitter equivalent of this really":

If anyone has any clues that would be helpful.

Another approach might be to use java and to create an array of balls from a basic class, either from Java or within the max patcher. You can apply different physical forces like friction, etc. Herewith a super basic and simple port of a processing example with a bouncing ball.
In the case of your youtube example, I would suggest to capture the balls and use a slab chain to create their color and texture(use the capture attribute).
Let me know it this helps!
BTW, Nice example Kyred!

Hello Ad.
Maybe you will need to compile the java file yourself, either by using the quickie or the terminal(if you are in OSX):
choose the folder where the java file is, the type something like:
javac -classpath /Applications/Max5/Cycling ’74/java/lib/max.jar

let me know if it works!

Could it be a java version issue ?

I created a whole bunch of interfaces like this a few years ago using JS and LCD. They still crop up on the forums once in a while.

Here’s a link to download them…

You can see / hear some videos of them here…

Cheers, Jules
