摘　　要：为了保护现有的秦汉文化遗产和提高人们参观博物馆的便捷程度,提出了通过构建虚拟秦汉博物馆网站来达到这双重目的的方法。对开发过程中使用到的物体几何建模、用户交互行为、场景导航图等关键技术进行了研究。重点分析了VRML中虚拟场景交互实现所采用的非编程和编程两种实现方法,并给出了两种交互方案的详细案例。提出了一套适用于VRML虚拟博物馆的虚拟场景优化方案,该方案在保证用户流畅漫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。最后在网上建立起一个功能比较完善的虚拟秦汉博物馆。To protect the existing cultural heritage of Qin and Han dynasties, and improve the convenience of visiting museums, the method of building a virtual museum of the Qin and Han is presented. Geometric modeling, user interaction behavior, navigation and other key technologies are studied. Non-programming method and programming method of virtual scene interaction are analyzed mainly, and these interaction programs with examples are achieved. An optimization program of virtual museum based on VRML is presented. The program can ensure that customers view roaming system smoothly, and solve the details of the museum exhibits display problems. Finally, a virtual museum of Qin and Han dynasties with relatively perfect functions is established on the Interact.
