The CAVE™ Virtual Reality Theater

Developers: Carolina Cruz-Neira, Daniel J. Sandin, Dave Pape, Greg Dawe, Thomas A. DeFanti


The CAVE™ is a multi-person, room-sized, high-resolution 3D video and audio environment invented at EVL in 1991. Graphics are projected in stereo onto three walls and the floor, and viewed with active stereo glasses equipped with a location sensor. As the user moves within the display boundaries, the correct perspective is displayed in real-time to achieve a fully immersive experience.

Bright Advanced Technology (BAT) CAVE™
In June 2001, EVL built the next-generation Bright Advanced Technology CAVE™, or BAT CAVE, using Christie Digital Systems’ Mirage 5000 projectors - the first DLP-based Active Stereoscopic projector - and near-black screens for higher contrast.

The BAT CAVE’s brightness, clarity and enhanced depth perspective produce more captivating real-time, real-life projection simulations than previous CAVE™ technology.
