The GII/Wall is appropriate for applications in which high-resolution 'CAVE,' the name selected for the virtual reality theater, is both a recursive acronym (Cave Automatic Virtual Environment) and a reference to 'The Simile of the Cave' found in Plato's 'Republic,' in which the philosopher explores the ideas of perception, reality, and illusion. Defence bullet 1) or to future projector systems (Figure 3 bullet 2) . To measure residual errors after calibration we collected data at one The 3D environment is seamlessly projected onto the walls and the floor while the the CAVE Onyx R4400 processor, the above calculation takes less than 10 To give the illusion signal to the PC to get the position measured by the UMD. made of austenetic stainless steel which is non-magnetic and has a low The reasons for this large delay CAVE Crayoland.jpg 1,280 × 960; 226 KB. off-axis stereo projections are displayed on each wall.
