Sound processing software controlled by the VR
environment is instrumental in making VR a "performance medium."
Fools Paradise is being developed using the CAVELib,
developed at the Electronic Visualization
Lab at the University of Illinois at Chicago and distributed
by VRCO, and the Ygdrasil
scripting environment that talks with the CAVELib and OpenGL
Performer. MaxMSP is
used for sound processing.
In the early stages of Fools Paradise, Paul Hertz
saw the necessity of creating sound processing software that would
be controlled from the VR environment. He developed sound spatialization
software for Ygdrasil using MaxMSP and Open Sound Control. The effort
was supported by the Center
for Art and Technology and the Center
for Interdisciplinary Studies in the Arts, Northwestern University,
and aided by the Electronic Visualization Lab, University of Illinois
at Chicago. The Ygdrasil nodes to interface with MaxMSP were written
by Joseph Tremonti, at EVL, in 2002. Nathan Wolek, a recent recipient
of a PhD in Music Technology from Northwestern, provided invaluable
support and code for MaxMSP. Alex Hill, who is currently finishing
his PhD at EVL, provided invaluable assistance with coding in in
Ygdrasil and with VR software and hardware in general. He provided
revised code for the Ygdrasil OSC nodes.
The sound processing software handles sound spatialization via
scripts from Ygdrasil more or less automatically, but can be customized
to handle any desired form of audio signal processing with a VR
control interface. In effect, it turns a VR environment into an
instrument for musical performance. The alpha release of the ygMaxTools
software is currently available for download. Future releases will
be posted on the web site of the Center for Art and Technology.
The Ygdrasil OSC nodes will be available sometime soon from the
Ygdrasil web site at EVL.
Please contact Paul Hertz for information on the sound spatialization
software.
