Abstract: Focused on the Visual System of Vehicle Simulator, a modeling method is presented, by combination of image modeling with geometry modeling together, to achieve better simulation effects with less system cost.An optimized and high-fidelity visual environment with some special effects of fluid and multi-texture level of some models is implemented based on the "Shader" technology in Cg.To satisfy the special immersive requirements of virtual driving training system, the distributed multi-channel projection and display system of high quality is developed based on the Computer Cluster Technology.And the distributed real-time interactive session and driving is realized in the same scene through network.The outcome is useful for study and development of distributed interactive simulation system.
