Paper Abstract

This paper describes a computer program which allows a user to semi-interactively navigate through a pre-recorded environment. The experience is achieved using a set of stereoscopic video sequences which have been recorded while walking around the various pathways of the chosen environment. In the completed system,the stereoscopic video sequences are played back in a sequence such that the operator is given the illusion of being able to continuously and semi-interactively navigate through the environment in stereoscopic 3D. At appropriate decision points the operator is given the option of choosing which direction to continue moving - thereby providing a level of interactivity. This paper discusses the combination of two recent advances in computer technology to transfer an existing video-disk based stereoscopic video walkthrough to run entirely on a PC. The increased computation power of PCs in recent years has allowed reasonably high-quality video playback to be performed on the desktop PC with no additional hardware. Also, Liquid Crystal Shutter (LCS) glasses systems are now widely available allowing high-quality stereoscopic images to be viewed easily on a PC. The demonstration system we have implemented interfaces with a large range of LCS glasses and allows the exploration of stereoscopic video walkthrough technology.
