Stretchy Lines With Quartz Composer and TUIO

Stretchy Lines With QuartzComposer and TUIO

I really dig the end result of this hack. Using Quartz Composer and TUIO, this project dubbed "Stretchy Lines" has came to life thanks to that handy depth sensing wonder toy Kinect. The setup includes a Kinect perpendicular to the table. The TUIO Server detects objects within a specific range, and then a calibrated projector draws random lines around the objects detected.

TUIO sends objects coords using OSC protocol to Quartz Composer, and then the graphic is rendered using custom Quartz Composer patches.

If you want to get set up with something similar to this, be sure to visit Ryan Channelor's site and try out Synapse Kinect. The developers of this hack did everything by scratch but I found Synapse Kinect to be a great jumping off point if you're just getting started.

The developers used KinectTouch to send TUIO coords which can be downloaded from and TUIO Quartz composer Client to receive TUIO coords inside QC -
