A virtual walkthrough system is built to demonstrate the unique capability of our wide field-of-view (FOV) head mounted projective display, which can theoretically achieve more than 180 degrees of horizontal FOV by utilizing a half-silvered hyperbolic curved mirror. A fast rendering algorithm developed for image distortion correction and performance analysis on the rendering speed and precision of distortion correction are described. The developed virtual walkthrough system has successfully provided the observer the sense of presence at an interactive frame rate.
