虚拟现实技术的应用---基于VRML技术的城市之旅 论文关键词：虚拟现实 城市规划 建模 仿真

论文摘要：随着虚拟现实技术的出现，城市规划建设发生了革命性的变化。而虚拟现实建模语言VRML正是相应其产生的，人们可以根据自己的丰富的想象力模拟构造出任意模型，从而实现城市规划的预见。当然，也可以从模型中发现缺点和不足，从而做进一步的改进和完善。本文正是基于这种技术和VRML开发工具实现了城市的仿真，能够使政府规划部门、项目开发商、工程人员及公众可以从任意角度，实时互动真实地看到规划效果，更好地掌握城市的形态和理解规划师的设计意图，公众的参与也能真正得以实现(www.51wendang.com

本文研究的主要是虚拟现实技术在城市规划领域中的应用。意义在于针对现代城市建设的盛行，利用环境学、工程学、规划设计等的综合，将虚拟现实技术运用其中，实现对城市的仿真，更真实、鲜明、生动地展现城市面貌，便于对城市规划的可行性研究，有利于城市的规划，建设和完善。

Abstract ：The city planning and layout have been revolutionized by the advent of the virtual reality technology. And Virtual Reality Modeling Language happens to come into being going with it. People could construct any model according to his imagination, consequently the expectation of the city planning can be achieved. Certainly we could find out the error and insufficiency, so that we could modify and improve it. The article bases on this technology and VRML exploitation tool to implement city emulation. It can make government layout department, project developer, engineering person and public set eyes on layout result in spots and commutatively by applying VR technology, and make them grip the city’s conformation and understand the purpose of the designer, and the participation of the public could come true.

This paper is mainly about the application of the virtual reality technology to the city planning. The significance is that it can realize city emulation by applicating euthenics, engineering, layout and VR technology. Consequently we can show the more real, brilliance, dramatic city’s visage, so that it makes the feasibility research of the city planning more simple and it in favor of city planning, city’s construct and city’ perfect.
