live drawing w jitter & wacom tablet


    Feb 17 2006 | 10:18 pm
    hi all, i've been doing live drawing performances with improvising musicians for a while now, using a wacom tablet and corel painter - i choose brushes and color on the screen of my powerbook, and i paint the stage with a projector thats hooked up to the video out. it's a solid setup but using painter is a bit of a bastardisation.
    now i wanna move on to using a real live performance rig. ideally i'd like to be able to change color/brushes with a midi keyboard.
    also i imagine it'd be cool to have the line fade with time, so i can keep drawing over the same image without too much visual build-up.
    my question: is jitter a viable option for achieving this?
    my concerns are whether i can aproximate the smoothness of the painter brushes, and whether something like this is achievable with a reasonable amount of effort.
    i'm a newbie to jitter but i have some experience in c++/openGL/mel script so i'm not scared of getting my hands dirty.
    any advice?

      thanks guys!
      nesa, i couldn't find the patch jean francois mentionned in the archives. do you still have it?
      i found a very basic wacom painting program at http://itp.nyu.edu/~rd64/lipp/
      but i guess i'll try to build a patch from scratch so i know what's happening.
      on to the tutorials!

      i've seen someone do exactly what you're talking about, with a Wacom and live painting in some sort of OpenGL program, with colored lines fading and swirling. It also reminded me (a lot) of Golan Levin's Yellowtail (http://www.flong.com/yellowtail/) I saw this guy play at Subtonic Lounge in New York city sometime a couple of weeks ago, but I couldn't find out his name. Sorry to be vague, but if you find out who it was I'd like to know too, it was an excellent performance.

      jean francois: thanks, don't know why i couldn't find nesa's patch before, got it now. great stuff to start off with.
      evan: thanx for the yellowtail link, that's inspiring. and i'll look around to find out about who it was at the subtonic lounge gig.
      i also find that stuff amazing: http://www.ni9e.com/graffiti_analysis.php especially cos it doesn't rely on a wacom for input, which i find kinda limiting if ur used to working with traditional media.

      See jsui_splinestuff-example.pat for one way to achieve this with Sketch, using the brush textures. Could easily be translated to a jit.gl.sketch implementation.

      The guy doing OpenGL drawing at SubTonic was Joshue Ott. It's a program called superDraw that he's been developing in Processing (http://www.intervalstudios.com/superdraw/index.html). I was very impressed by his performance as well.

      wait a minnit....I believe "Super Draw" was one of the original macintosh paint programs. I think it was Super because it did bitmap AND vector in the same program - not like macpaint or macdraw which were 2 different apps.
    • Feb 20 2006 | 11:12 pm
      well, Josh's program is superDraw, not Super Draw. ;) :p

      for people who are interested in wacom painting, here is a link to a chinese-brush painting program http://www.cs.ust.hk/~cpegnel/VCB/

      thanks everyone.
      i've had a look at processing - man thats really cool stuff. actually i'm leaning towards using it instead of jitter. i've implemented a quick prototype of what i need, still minus the midi capabilities. but that shouldn't be much of a problem either.
      it's looking like the way to go for me, especially cos it's open source.

      The web version of superDraw is incredible!
      Does Joshue offer a download, or does you have to familiarise yourself with processing first?
      Magic.

      No, Josh hasn't put out a downloadable app as yet. Let him know you're interested! It's his first time writing a visuals app and he's uncertain how many people would like it.

      really, build it yourself - Max is fun, pretty forgiving and a lot to explore
      . it wasnt that hard of a patch to make if you think slowly through the methodology. Josh's superDraw does a lot, but to do basic drawing within max 2d to 3d - use the wacom object (search for it), and use openGl screen2world functionality within javascript
      it can be done - ive got a basic implementation working on my end - and its fun.

      And, like the space program of old, you'll also likely get tang, teflon, and space food sticks in addition to those bootprints on the lunar surface.

      hi nesa! still have the brushes for your wonderful paint program? the original link is offline... http://tinyurl.com/2ua6ok

      hello,
      the program i was starting to program when i opened this thread has come some way since then - check www.tagtool.org
      the current version is written in C#. There's also network capabilty so you can have several people draw together over tcp/ip.
      also speaks midi and (soon) osc, so you could hook it up with max/jitter i suppose.
      it's actually an open source project so if anyone is interested in abusing it for their purposes, go ahead... although we still need to work on documentation to make things more accessible. we'll be posting progress on www.tagtool.org/developer.
      all the best, markus

      mador, this looks very verygood. u wrote a miniJitter. respect

      thx - although all credit to Richard Radlherr & Paul Schabl. I did the original prototype of the software in Processing but soon hit performance limits. They implemented the C# version which actually has an underlying node editor a little bit like jitter so we can easily tweak & change functionality for different projects.

      hello yair!
      sorry: that page died, here's the new link:
      @marcus: really nice project!
      best wishes, nesa

      It looks like jean francois' posts were erased somehow. Where can I find nesa's patch? I tried going to the google page, but the link for the new website only opens up an html in safari where all the links are question marks. I know this is an old thread, but I'm very interested in wacom drawing, so if anyone can help point me in the right direction I'd appreciate it!

      I believe is this one below, the link to download the brush tips is in Nesa's last message. Happy New Year! g

      Thanks, giorgio! That's a huge help! Happy new years to you as well!

      Hello i'm working on a spray simulator, This patch is really nice, but is there a way to create intermediate points when the cursor go too fast with jit.gl.multiple JavaScript or stroke like in photoshop. thanks
