Examples of CaveUT Implementations

The School of Information Sciences at the University of Pittsburgh, in cooperation with the VISIC Lab (see below) set aside a room and bought the equipment for a CaveUT Based immersive environment. It is intended for general use in the school for student and faculty research projects. It has four projectors, two projecting onto the back wall of the room and two more projecting onto the sides. Essentially it is two two-walled caves stuck together. This image shows a student, Lyle Seethaller standing in front of his Virtual Audubon Exhibit. which he built using the authoring tools that come with Unreal Tournament. CaveUT can display any virtual environment built for Unreal Tournament, without modification.

The Flatworld Project is a joint project of the Institute for Creative Technologies (ICT) and the Integrated Media Systems Center (ISMC) both at the University of Southern California. Flatworld is using CaveUT for interface prototyping. The image here shows CaveUT displaying on their curved screen display, which is still under construction.

CaveUT was originally developed on the BNAVE, a PC-based CAVE-like display the Medical Virtual Reality Center, Department of Otolaryngology, University of Pittsburgh.

To the right is a picture of the BNAVE showing DM-Suntemple, a virtual world that comes prepackaged with UT. The screens are at an 80.5-degree angle to each other, and we are looking straight into the corner. (The image looks bent because the camera taking this picture could not be placed in the ideal viewing location; the image does not appear bent to someone standing in the correct position before the screens.)

The BNAVE consists of three walls arraigned in a "U" around the viewer. A fourth projection surface has been added to the floor.

Each wall is a rear-projection screen. Onto each of the three screens is rear-projected projected the SVGA output of a dedicated PC.

Illustrated here is the portable V-Cave, which was demonstrated at CHI 2002 and will be shown at the Ultra Unreal and HFES 46th meeting events.

This setup uses tripod-mounted projectors to project onto screens stretched from a collapsible frame made from PVC pipe. The basic configuration is much as same as in Figure Two.

More screens can be added to this arrangement; the only limits are the Unreal Tournament 2004 limitation of thirty-one screens, and the limits on the fabrication skills and patience of the people putting together the CaveUT setup.

The screens can be front or rear projected, or can include some of each. foo_filesThe only requirement is that a user in the ideal viewing location should not be in the way of any projectors.
