Recently introduced 3D games, game editors, along with gaming software offer great potential for delivering three-dimensional, collaborative virtual environments for online audiences. These capabilities have significant potential in architectural visualization. The University of Missouri-Columbiais Emerging Technology Group developed the Virtual Campus Project introducing the university campus to prospective students through the Internet. Fascinating quality, seamless real time rendering, and smooth navigation are enough to impress visitors. However, the developers had to use eye measures and guesses based on photos rather than architectural drawings for initial 3D computer models. The absence of a precise scaling system as well as not being able to recognize a standard 3D architectural drawing format in a virtual environment were the prime generators of this paper. One important goal for this paper is to suggest architects the potentials of using universal or exchangeable formats of 3D models with accurate structure data to build virtual models. A second goal is to provide better understanding of potentials in 3D game engines for virtual representation of architecture.
