||The Interactive Dance Club at Siggraph
98 in Orlando July 20-23 took a bold step in advancing live interactive
entertainment. It put the control of the visuals and sound into
the hands and bodies of people in the club, leading to a coherent
and fun-to watch experience.
|Both the 3D visuals and the audio
were being created and mixed live. Nine "zones" containing
input devices allowed people in the crowd to affect and guide
the visuals and sound.
||While 6 simultaneous live 3D animations
were being guided by 6 or more crowd members, 12 sound sources
managed by PiOS were generated by synthesizers and sequencers.
The Interactive Dance Clubbers were also treated to
a Raytheon infrared heat camera, which was pointed on the crowd.
Its satellite-quality image was displayed on a large projection
screen. In addition, two lounge areas had couches, large TVs
and joysticks that let any "voyeur" have control over
cameras located in the main dance area.

The team of 15 IDC artists and technicians felt the
potency of this combination of live elements. But being an experiment
involving all volunteer time, the IDC was finally assembled and
tested only two days before Siggraph 98 opened up.
Greg Hermanovic, in charge with Judith Crow of the
live 3D visuals: "We all were shocked and levitated at the
same time. The synergy of the live visuals, sounds and lights,
with the strong syncronization of it all took us by surprise!"
Synesthesia, the creators of IDC, set out to create
a new form of interactive entertainment. They chose Houdini as
their computer graphics solution as it provided a realtime, fast,
reliable tool for Live 3D Visuals.
