raw depth values from the kinect, originally 11 bit unsigned short, so in the range 0-2048, but generally only 0-1100 or so. converted to 32 bit floating point values. saved as a headerless stream of floats. opened in photoshop as a 4-channel 640x480 image. this way CMY inherits from the mantissa and K from the exponent (i think).
the scene is originally from indoors at makerbot industries, two computers and some electronics.
multiple kinects on the same computer sending skeleton tracking data from openni. working on aligning the kinects to each other next...
Binning lots of particles with mouse interaction in realtime, simulating collisions.

Tim Gfrerer is a desinger and coder who explores new ways to create narrative experiences. He works in public service broadcasting and new media. His professional origins rooted in concept development for radio and in journalism, with an academic background in design and new media, his practice seeks ways to broaden and connect these fields. Before moving over to London and to writing mainly stuff for machines, he wrote for human beings and lived in Vienna; there keeping himself busy as a Journalist for ORF, and as a creative producer for Radio FM4.

5uper.net Over two days we’ll walk through complete examples introducing the OpenFrameworks system. Together we’ll build a simple drawing application, do image processing, learn how to network an installation using OSC, and program interactivity using real time face detection. The second day will be an open coding jam where participants will be free to begin pursuing bigger projects. We’ll be there to debug and give guidance on tackling your ideas.

Sensorial installation to bridge the gap between digital and digitally designed physical environments. The installation invites participants to engage with the tear-drop-like structure which is made out of paper and carefully crafted using parametric principles and computational methods. Participants use sound (noises) to engage with Capillary and it responds with visuals that remind viewers of natural phenomena when liquid flows against gravity.
built with Rhinoceros and openFrameworks

Electrons by Frank Marino
fourth fm scan. still only 256 images.
the technique here is to use the previous steps as an initial guess for the properties of the sine wave at each pixel, and then run levmar nonlinear optimization from those guesses to arrive at an ideal set of value.
i'm only showing the difference between this one and the previous, because the change is so subtle.
this takes about 15 minutes for 640x480x256 and may not be worth the added accuracy, but it's good to know it's an option.
Worked with O Cubo in creating an interactive floor for GNR (the portuguese national guard) as part of the celebrations for the centenary of the portuguese republic.
It allowed the visitors to look through several historical archive images.
The exhibition ran for 3 weeks during April at GNR's headquarters in Largo do Carmo, Lisbon.
It was created in C++ using OpenFrameworks with OpenCV and OpenGL
