Based on Double District by Saburo Teshigawara with Volker Kuchelmeister, 2008
This work explores interactive stereoscopic 3D scanline visualisation applied to a dancer’s body in motion. The result is a ever evolving abstract shape or form controlled by a simple user interface. Visualisation is done in realtime and stereoscopic 3D. Using a horizontal vs. a more common vertical scanline is necessary to preserve the horizontal image disparity or parallax between left and right eye view. Without stereopsis is not possible.
This video material is based on stereoscopic footage I captured for Double District, a multi-channel steroscopic video installation by Saburo Teshigawara with Volker Kuchelmeister (2008).
A series of experiments with this technology culminated in a performance at ZKM Centre for Art and Media Karlsruhe. Music composed by Ludger Bruemmer. The multi-channel sound is spatialised in the ZKM Klangdome, a state-of-the-art 48 channel sound studio in the ZKM Cube. The spatial extend, localisation and spread of the multi-channel composition is responsive to the horizontal extend of the image, the stereoscopic 3D depth and luminance extracted from the video. Software: Quartz Composer and Zirkonium. Public performances during the 3 day Beyond Festival at ZKM Centre for Art and Media Karlsruhe. May 26-29 2011.
Interactive version: A user can interact with the work by adjusting the vertical position of the scanline. A rotary knob acts as a simple and intuitive interface. This dynamic change in position has a dramatic effect on the visuals, more or less of the body is revealed and the result is ever evolving.
The idea of using a scanline or slit scan technique for video is nothing new, as Golan Levin’s excellent catalogue demonstrates, but to my knowledge, this is the first time his is done in stereoscopic 3D.
