Hi everyone, I was wondering if anybody has really tried to get blob tracking working in quartz composer. I have been playing around with it recently and I think that I have created some promising stuff. This is a picture of what I have been able to do with the filters in quartz composer. All I need now is a way to track the dots and then output them to some other application.

Hi,

Please post the quarts file so other people can look at it.  For output you want it to format it as TUIO, which is built on OSC, which is built on UDP.  That is pretty much the de-facto standard for Multi-Touch communication.

Ok, here it is. Change the video input to use a different camera.

Looks like fun, but I get a ton of fetureplotterplugin missing errors.

This looks good, but i’m more interested in getting bbtouch to work with quartz comp via TUIO.  Can you give it a try and see if you have any luck? You can find BBtouch via SVN checkout. Look for the addres on Ben Brittens blog AKA Panda! He has today released TUIO for BBtouch.  There is a TUIO QC patch on reativisions page.  Good Luck!

The quartz patch wont work with Leopard though, I have a version that does if you need it?

Yes please! Can you put a link here?

Let me reboot into Mac OS and find it.  I need to remember where I got it to give proper thanks etc too, don’t want anyone thinking it’s my own work!

It belongs to Chris Wright of Kineme.  http://kineme.net/

I have no access to my space from here, so if you can give me an e-mail address I’ll zip it and send it over.

Perish the thought!  Just trying to get bb touch talking to QC via TUIO on OS x10.5 but the reactivision patch only supports fiducials, Damn my FTIR setup!

nice on its

Thanks a lot for the help. The only problem is that the actual blob tracking patches for quartz composer must be run under rosetta which really slows it down. Does anybody know if there are patches out there that will run not in rosetta? Also, thanks for pointing me towards that leopard tuio patch.
