Investigation of Vehicle Driving Simulator by Distributed Virtual Reality Technology

We have introduced the latest investigation on the vehicle driving simulator by the distributed virtual reality technology. It is an integrated software and hardware system that combines virtual and network environments. The main research is focused on vision system, which includes the exterior and interior scenes of vehicles. The following technologies have been investigated: NURBS-based auto-adjustment and generation of the road surface texture(including road signs), MipMapping generation by contour lines, no-aperture slice technology of the model and its texture, and experimentation and interaction in the simulation environment based on the physical properties of the model. Some examples of this vehicle driving simulator system are also given, such as when selecting vehicles, weather, time and some kinds of road status.
