A CAVE tm is a room in which the user is presented with high-resolution stereo-pair images projected in real-time on 3 walls and the floor. When viewed through lightweight shutterglasses, the left/right stereo images are presented separately to the left and right eyes respectively, producing the illusion of 3D objects appearing both within and beyond the walls of the CAVE. The images are presented with reference to the users viewpoint, which is continuously updated via a head-tracking unit; thus even as the user moves around in a CAVE the environment displayed will always be perspective-correct.
UCL's ReaCToR system incorporates a variety of technologies to enhance this illusion of immersion:
The ReaCToR system was supported with a £900,000 grant from HEFCE's Joint Research Equipment Initiative. The installation was performed by Trimension Systems; the computing power is provided by a Silicon Graphics Onyx2 InfiniteReality2 graphics rack system, and the audio system by Arup Acoustics.
