Caption: Computer Simulation of Virtual Reality - Architectural Walkthrough. This computer model of the hallway of a house in Scotland designed by architect Charles Rennie Mackintosh was created at the Cornell site of the Science and Technology Center for Computer Graphics and Scientific Visualization. The model dynamically displays lighting and textures in this complex environment as the viewer "walks" through the virtual reality setting. This research project was presented in a multi-site research seminar conducted over high-speed network lines. Participants at all sites could conduct a remotely steered walkthrough in real time.
