摘　　要：探讨了望虞河工程虚拟视景系统的结构、功能和构建方法;讨论了虚拟视景建模和交互驱动问题;针对视景复杂无法实时驱动的问题提出了模型分割和软件加速的解决办法,并利用DirectX三维引擎技术在微机平台上开发了望虞河工程虚拟视景系统.An introduction was given to the structure and function of the virtual scene system and method for its construction. The method for modeling of virtual scene and problem related to interactive driving of the system were discussed. Then, a model separation and software acceleration method was proposed for real-time driving of complex scene, and the 3-D DirectX engine technique on the platform of the micro-computer was used to develop the virtual scene system for the Wangyuhe River project.
