Experimenting with DOF

I will have the whole summer to think about the ‘tweaks’ I want to do to the ‘Worm Songs’. So I’ve spent a good deal of time trying different things for the visual rendering of the system: implementing Data Visualization to the material, toying with some geometry twists and, of course, shaders.
DOF is a rather interesting( and sometimes expensive) effect. Lately SSAO and DOF are taking most of my ‘sketching’ time. Herewith some results though I am not sure this will make it to the final version of the ‘Worm Songs’.

Working today at the studio with Jerome from MCDance using glass projection and hand gestures. Explorations are lovely, finding beauty keeps the research magic and promising…
Some of the motions are actually very poetic, I think we will continue exploring on this direction!

Garden of geometries

December 6, 2010 Leave a comment

Past month I finished a really nice project called ‘Electric Gardens’ with the trio ‘Electronic Hammer’:;

One of the premises of the project was to design an interactive system that would react to the gestures of the performers, either as audio analysis or data coming from their computers/instruments. As a result I designed a system that would keep me occupied for a while as it presents a lot of possibilities.
I designed most of the piece thinking in ‘scenes’ hosted on a system that would allow fast and simple transitions. The image is a kind of ‘modular cinema’ where each one of the parts could have their own visual ‘world’ encapsulated.
In terms of technique, I designed most of the piece using glsl shaders and lots of java classes for deforming and handling the geometries. Many of the materials were sketched using code tools( basically Cinder) and then ported to jitter, which has a more ‘performing’ profile and has a range of friendly facilities for MIDI and audio analysis. Some of the shaders( those of light models) are ports of hlsl shaders.
