Mac OS X 10.6 (Snow Leopard)
Hi! This is a composition a made for fun. Could you give any suggestions?
A simple slideshow browser using Kinect camera for interaction.
A new plugin in the Carasuelo OpenCV bundle : Blob Tracking. I implemented the cvblob library and externalized a lot of parameters to prepare the image, and to set the tracking accuracy. It's supposed to work with 10.6 and 10.7 in 32/64.
It outputs a structure of blobs with coordinates, angle, and tracking datas (has been active for x frames, has been inactive for x frames, exists since...).
An image output is available, with the possibility to output the intermediate image. It runs quite fast on my MBP 13" even when the frame isn't resized (640x480).
The 3 example comps (Blob Tracking, Contours and Presence) are documented. I have to work again on these 2 plugins to make them fit a CVImage class I wrote to simplify OpenCV use.
There's a big issue on the image dimensions, as I have a trouble with "special" width on input images, but in most case it should be ok for everyone. I'm working on it, but if someone has an idea...
Please tell me if it works for you !
I would be glad to see what you do with it.

With this comp you can control a differents meshes. You can rotate, change colors, and make some funny things. You need an IPod Touch, or an IPad running TouchOSC app, and some more things.
You need to download the zip file, they have the .dae files, a readme file and the TouchOSC files.
You need to install some patches from Kineme: the Kineme Audio Tools and the Kineme GL Tools. Additionally you need to install the Hexler's qcOSC plugin, you can found it at
This is an excersise I made for my vjing session, you can use it, and modify it as you want. You can change the .dae files if you like too.
If you have any question you can write me to:

I'm not an expert, so, the composition could be better, if you can improve it, please, send me your file, I like to learn from you. Thanks a lot, and thanks to the QC community.

Traveling from the future to the present? If yes, that´s your comp.
Just a string with a countdown from around 2040 untill the exact current time. Necessary Counter plus from http://code.google.com/p/rdqcutils/
This composition is based around a shader that creates many spheres, with lighting, using only the fragment shader. It's based on functions found at: http://www.iquilezles.org/www/articles/distfunctions/distfunctions.htm
...and also heavily informed by many of the examples at glsl sandbox, and probably tons of other related demoscene type shaders I've seen.
I wanted to take a distance function, create a shape with that function, and then create a grid in x/y/z with it, ala many traditional graphics examples. So, this shows how to create an object in the fragment shader, repeat it many times, and light it in a basic way.
