On 18^th of May 2009 we were able to setup the GeoWall system for the first time. As visualizer tool we use 3DVisualizer from: http://www.keckcaves.org/software/VISUALIZERCG to visualize CitcomS simulation data in 3D. We would like to thank Magali Billen, Oliver Kreylos and Bill Broadley for the help provided in compiling Vrui and 3DVisualization routines on the GeoWall workstation. There is no head tracking for the moment, and probably in the near future we will upgrade the system with this new capability.
