Walkthrough-Exploring Virtual Worlds

Abstract

A virtual world system is a computer graphics system allowing natural real-time interaction with a 3-dimensional model world. Walkthrough is a virtual world system for architectures and their clients to explore buildings before they are built, so as to iteratively refine their specifications. Much of our virtual-world research at Chapel Hill has involved molecules or human anatomy. In neither of these applications does one know exactly how the virtual world should seem to the explorer. In Walkthrough, on the other hand, the researcher can easily tell how closely the virtual world matches the real in the ways that matter. Any virtual-world research project must continually improve in four aspects, shown in the figure. The videotape, which constitutes Part II of this report, shows where we are today, and gives short previews of some of the advances not yet integrated into the system. Keywords: Radiosity lighting models, Man machine interface.
