Virtual Reality Center using immersive curved display

This article is going to describe our effort to build a Virtual Reality Center using several technologies such as 3D world model development, 3D sound generation, mutli-projector cylindrical display and 3D image processing. The virtual reality center uses four data projector to project a large seamless picture to a hemi-cylindrical display from the back of screen. We use Dolby Digital Surround EX sound system with a 7.1 channel speaker. A software engine does any necessary transformation like intensity and edge blending and image warping to prepare input data for each projector. A stereo camera used to track the viewer who determines the directions with an Infra Red pointer. The camera produces a feedback for server to update the 3D world model. This virtual reality center can be used in different areas like as scientific visualization, industrial design, entertainment applications and training simulators.
