This sample composition demonstrates the CamShift object tracking method.

In this example an initial Haar detection will be performed to define the tracking area which get passed over to the CamShift tracking. The tracking results are send through a Kalman filter to stabilize and predict the object movement (e.g. when the object is covered or only partly visible).The tracking results will be constantly re-evaluated according to a given threshold and the CamShift parameters automatically adjusted.

Still a lot of work in progress and plenty to optimize...

The attached CVDetection.plugin will need to be copied to (your user folder)/Library/Graphics/Quartz Composer Plug-Ins first

This is a speed-optimized version of the Icosahedron shader posted here: ( http://kineme.net/composition/gtoledo3/Icosahedron ).

What remains is basically the depth equation...licensed under GPL/LGPL.

To paraphrase my icosahedron post (http://kineme.net/composition/gtoledo3/Icosahedron), I was checking out the source for fragmentarium (http://syntopia.github.com/Fragmentarium/ ...licensed under GPL/LGPL ) , and setup the shaders to work in QC.

This is an Pseudo Klienian Menger fractal running in QC's glsl shader patch.

It's fairly slow, so don't expect it to be a real time thing at high quality settings. :-) It's a little snappier than the icosahedron... I'd guess it could be made to run faster by making the lighting and color routines simpler.

I modded Goto 10's awesome, Awesome LIne Drawer patch and added some kinect funcitonality. Left and right hands both draw lines in 3D space and your torso controls the movement of the camera. It's super fun.

I'm attaching a Quartz only version as well as a VDMX version with a VDMX template with a custom Kinect control surface to use as a data source. For the quartz version I used the help of the tryplex toolkit and synapse. For the VDMX version I used Synapse and the quartz passthrough plus max patch provided in the synapse zip to send OSC to VDMX.

Thanks!
