摘要： 介绍了基于VRML的汽车虚拟驾驶系统的设计,采用3Ds Max建立城市建筑、街道、路灯、道路维护设备及标志等静态物体的三维几何模型,将这些几何模型装配成城市模型,将其转换成VRML格式,然后,采用PamllelGraphics的Internet Scene Assembler工具装配具有动态行为的几何模型并进行动态行为建模,如交通信号灯、汽车、行人。该工具使用基于VRML语言的可视化界面进行建模,使用很方便,效率高。动态行为使用VRML2.0结合Java Script进行编程。开发的虚拟汽车驾驶系统可以在Internet上发布和游览。

Abstract: This paper introduces the design of a VRML-based driving simulation system. After the geometric model of the static object such as city buildings, streets, street lights, construction and maintenance equipments are created in 3Ds Max, they are transformed to VRML2.0 files. Then the Internet Scene Assembler of ParallelGraphics is used to assemble the city as a whole and other objects that have dynamic behavior and model the dynamic behavior of these objects using VRML2.0 and Java Script, such as the traffic light, walking person and car. This tool is based on VRML 2.0 and has a user-friendly graphical interface. So it is very easy and efficient to model complex virtual scene using this tool. The viatual driving system can be published and explored on Internet.
