Abstract

In this paper we present our work on modularizing and distributing a VR application – the Virtual Night Drive simulator. The main focus in our work is the simulation of headlights. The realistic but still interactive visualization of those lights is essential for a usable driving simulator at night. Modern techniques like pixel and vertex shaders and volume rendering help to realize the complex task of light simulation. But there are still scenarios, especially when having several cars with headlights in one scene, that require distributed setups to run the simulation in an interactive way. In this paper we present an architecture that supports several approaches of distributed light simulation, compare it to existing systems and give an outlook on what is left to do.
