Abstract: Virtual Reality(VR) technology has been widely used in recent years, but most of people feel to develop a VR system is too difficult . Combined with the requires of water conservancy and feasible technology ,this paper discussed a real time cruise system of visualized 3D project based on desktop VR system technology, the method of construction, transition and usage has been given. A practical system is implemented by DirectX.

摘要： 近年来兴起的虚拟现实技术在许多领域有着广泛的应用，但对于一般用户来说，它的应用开发是比较困难的。结合水利行业的需求和当前比较可行的技术，讨论了基于桌面系统虚拟现实技术的工程三维形象实时漫游系统，给出了模型的建立、转换及调用方法。并利用DirectX技术完成了一个实用系统。
