分布式汽车驾驶交互仿真系统的实现

An Implementation of Distributed Interactive Driving Simulation System

以驾驶模拟器的视景系统作为对象,提出了图像建模与几何建模相结合的建模方法,实现了以较少的系统消耗达到更加真实的视景仿真效果;采用基于Cg的"Shader"新技术,实现了虚拟环境中的动态流体特效和多层次纹理细节级别的良好效果;自主研发了基于计算机群集的多通道屏幕投影与显示技术,满足了沉浸式虚拟驾驶演示环境的特殊要求;实现了基于网络的分布式多客户、同场景的交互驾驶与实时通信对话.文中方法对分布式交互仿真系统的研究与开发有一定的参考价值.

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.
