Abstract
Computer rendering and simulating real world environments has traditionally required the use of expensive and dedicated graphics workstations. The high price of these computer systems limited the range of their applications. In the past few years, there has been an explosion of new low-cost PC based 3D accerlerator boards. The technology has matured to a point at which these boards are able to deliver an incredible performance for the price. During the first phase of this study, various PC based accelerator cards were assessed. The 3DFX Voodoo2 chipset was judged to offer the best performance for price. The power of this technology was demonstrated via a custom computer graphics (CG) demo simulation in the second phase. A 400 Mhz Pentium2 system facilitated the simulation, processing over 500,000 polygons per second with a very high level of realism. A large terrain area was simulated with a continuous level of detail for this demo. The demonstrated simulation has the ability to render objects (buildings, vehicles etc.), trees, fire and smoke effects. Weather effects, fog, and real time lighting were also explored in this work.
