DriS - A Virtual Driving Simulator

Abstract

A driving simulator is complex and expensive system. In order for the driving simulation to be convincing, its necessary to give reliable sensorial information to the driver. Usually, the driver is able to see a realistic image both in a large screen display or in a HMD. High quality audio information is also supplied. With in the development of DriS, a house made Diving Simulator of a car, we are trying to cut down the relation between performance and cost. We are developing some innovative optimization techniques, in order to obtain a faster and reliable screen update. Some of those techniques like hierarchical culling of back-facing polygons, hierarchical visibility preprocessing, and automatic model simplification, can dramatically improve the rendering time of huge scene databases. This paper provides a full description of the architecture of DriS, as well as descriptions of innovative optimization techniques used.
