General Characteristics of The CAVE
The CAVE is a large theatre sited within a larger room. The walls of the CAVE are made up of rear-projection screens, and the floor is made of a down-projection screen. High-resolution projectors display images on the screens via mirrors. The user wears special glasses inside the CAVE to see 3D graphics generated by the CAVE. People using the CAVE can see objects apparently floating in the air, and can walk around them, getting a proper view of what they would look like in reality. This is made possible by electromagnetic sensors. The frame of the CAVE is made of non-magnetic stainless steel to interfere as little as possible with the electromagnetic sensors. A CAVE user's movements are tracked by the sensors and the video adjusts accordingly. Computers control both this aspect of the CAVE and the audio aspect. There are multiple speakers placed at multiple angles in the CAVE, providing 3D sound to complement the 3D video.
