GL multislider / visualizations

Sep 13 2010 | 9:49 pm

I’m looking for a way to reproduce a line-scrolling multislider in jitter (for data visualization – would let me shine it up a bit). I’ve looked at jit.fill a bit but am not getting what I’m looking for (at least not yet). I’d rather not draw the whole thing out point-by-point as I’m looking for at 256-512 points, at least.

It might be helpful to know what kind of data you are trying to visualize.

here is a patch that acts like a multislider for audio, although it doesn’t let you click and drag value in. sorry it’s rough, it was a deadend on a project i was working on. check it out and if you have any questions shoot me back and i can walk you through it.

basically, the below is just a demo of the "line scroll" setting for [multislider], using [drunk] for input instead of something more meaningful. I’m just looking to recreate this "look" in Jitter so it can be a lil more flexible + sexy.

Ok Billy, check out the these patches. I wasn’t able to recreate exactly what you wanted, I don’t know how to fill the area the below the datapoint. The only other idea that I had to get a matrix to look exactly like the multisider is to use opengl to draw rectangles, but that would be a little intense. maybe somebody else knows and easier way.

I left your drunk in both patches so that you can plop in whatever is generating your data. Let me know if you have any questions and send me a message if you finish whatever project you’re working on…

this patch uses a counter and a setcell message to draw through the matrix. can be set to reset with each new line. I really like what comes out when it starts to draw over itself.

this patch is a little more interesting. it uses matrix feedback so that a matrix acts a little like the multislider. don’t have both patches open at the same time because the matrixes will mess with each other…

hey awdriggs that’s awfully good work if you cooked that up just for my interest! thanks! I’ll have to do some evaluation to see how flexible I can make the matrix. I guess the last question I’d have for you would be regarding how to fill in the spaces below the data points…otherwise, this has been extremely helpful.

I had some of those parts worked up while I was working on an interactive installation. check it out if you are interested, it is the voice landscape. The feedback I stole from luke dubois’ soundlump patch in the jitter examples.

you might be able to use jit.expr to write an expression that will fill all of the y values under your y datapoint. You’ll need a jit.iter to iterate through the y values and a set cell message. If I have a few minutes this weekend I’ll try to set one up. Try to learn our problems has taught/reminded me of a few things!
