为促进虚拟现实和数字化博物馆的发展，通过虚拟现实建模语言 (VRML)设计和实现平顶山市博物馆虚拟漫游系统，使来访者可以通过网络身临其境般地参观博物馆。对开发过程中使用到的物体几何建模、用户交互、导航等技术进行了研究，提出了一套适用于 VRML虚拟博物馆的虚拟场景优化方案，该方案在保证用户畅游本系统的同时有效地解决了博物馆展品的细节显示问题。最终建成平顶山市博物馆虚拟漫游系统，该系统图、文、声、像并茂，具有导航、漫游、交互等功能，能够实现播放控制和解说控制。

A virtual roaming system of Pingdingshan museum by Virtual Reality Modeling Language(VRML) is designed in order to promote the development of virtual reality and digital museum, and enable visitors to visit the museum in an immersive way through the network. Geometric modeling, user interaction behavior, navigation and other key technologies in the development process are studied. An optimization program of virtual museum based on VRML is presented. The program ensures that customers view roaming system smoothly, and solves the display problems of the details of the museum exhibits. Finally, a virtual roaming system of Pingdingshan museum with relatively perfect functions is realized. Thesystem is combined with multimedia, navigation, roaming, interaction and play control．
