Technical and space requirements: a darkened room, approx 4x6 m.
The graphic card renders the stereoscopic
and other effects with special drivers and directX graphical library.
Video camera signal with 'night-view' function, enhanced by infrared
light is analysed by pattern recognition and motion tracking software.
Morphed coordinates of previously captured 3D motion data of real people
are mixed together live with visitor movement and gesture data. The
object property database supports scene changes and calculations. Various
areas in the scene space trigger different parameters for animation,
visual and sound effects (like intensity, density, level of details,
etc.) The electro statistic field sensors trigger various modes, depending
of visitor presence. Hardware:
- 3 PCs
- 2 CRT (RGB) projectors (alternatively 1 projector)
- stereo shutter glasses
- video camera
- custom-built electrostatic field sensor interfaces
- MIDI in/out/mix interfaces
- 2 game joysticks
- blaxxun Contact VRML client with custom (C++) extensions: MIDI client,
SpaceMouse plug-in, TCP server/client plug-in, SQL (ODBC) client plug-in,
- EyesWeb video tracking/motion analysis software,
- Java applets for various specific AI algorithms.
