What makes virtual systems a reality

Abstract

If posed as a question, one possible answer to the title is: "sufficient resources." Given enough resources, sometimes referred to as infinite dollars, it is plausible that one can realize a life-like virtual environment, or the ultimate simulation system. For most of us, however, the fact remains that resources (time, money, processing power) are limited. Our objective then becomes to engineer solutions that satisfy the intended use of the product while remaining within bounds of the resource constraints. As simple as this focus may seem, it is often lost to two factors (1) getting caught up in the media hype of virtual reality and losing sight of the application and context, and (2) the inability to strike a realistic balance between affordable technology and the envisioned end product, i.e., the inability to come to terms with trade-offs.To prevent unanticipated disappointments, we need a solid understanding of the context and application of a simation system before getting carried away with the glamour of technology. This paper provides a top level examination of the complex issues associated with development and production of synthetic environments, and highlights some key trade-off elements.
