Research and Implementation of Ancient Architecture Roaming System Based on VRML

Technology of virtual random walk in building environment is one of the important contents of virtual reality technology, which has a broad prospect for application in the fields of architecture, tourism, military and computer game design. This paper introduces the principle of virtual reality modeling language VRML, analyzes its operating principle and basic characteristics. Then it introduces some related technologies of the ancient cultural sites of the virtual roaming system. It introduces in detail three-dimensional modeling steps and methods including geometric modeling, physical modeling and Behavioral Modeling. Then, it give a detailed analysis of the key technology and the program realization of the ancient architecture of the virtual roaming system with the construction of Miaofeng Mountain as the background. Finally, it introduces the web-browse module and the optimization mode of the scene.
