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.
