Virtual reality display renewal

点击翻译按钮获取中文摘要

IVY, the Immersive Visual environment at York, is used for a variety of tasks from visualizing complex scenes, to the generation of novel environments for psychophysical and human performance experiments. IVY is a unique 8'x8'x8' six-sided projective virtual environment powered by a cluster of high-end PC's with appropriate graphics cards. Each of the six walls of IVY are used to present rear-projected stereo imagery to the user within IVY. This surrounds the user with a high quality visual simulation of some alternate reality. In continuous use since 1999, a key element of IVY are the projectors used to present the visual display to the user. IVY's projectors were purchased in 1999 and are beginning to fail. This grant seeks funding to replace IVY's projectors so that it can continue to operate and facilitate innovative scientific research.
