摘要
虚拟城市场景的实现是虚拟城市设计的重要内容。阐述了虚拟城市的构建意义,描述了虚拟现实模型语言,同时,以VRML为平台采用制作实例的方式探讨了虚拟城市场景的建立。针对VRML文件传输大、渲染速度慢的不足提出了虚拟城市场景建模的优化措施,对于城市数字化建设具有一定的借鉴意义。
The application of virtual city＇s scene is an important step to design virtual city. This paper describes the significance of constructing virtual city and depicts virtual reality modeling language. At the same time, using the mode of design actual example,the paper discusses the construction of the scene of virtual city on VRML,and points out optimization strategy in the scene of virtual city＇s modeling aiming at the large file of VRML and the slow speed of rendering. It has some significance for reference to construct digital city.
