3D Graphics and Virtual Reality Applications in Decision Support System
This paper discusses the procedures of generating a 3D terrain visualization system which includes a basic GIS inquiry function, a navigation function and a dynamic change function. By using the WINDOWS XP system and Visual C++6.0, a pilot system has been established. The system can transform the DEM data into the 3D version in the screen and use aerial photographs or image data from the analysis procedure as a texture file in order to show photo-realistic details about the area. Through the control of transparency between two images, a dynamic change function can be realized. The 3Ds MAX software is used to make an active movie about the dynamic change. As a case study, the Yellow River Delta is used as the study area in order to show the past and present situation of the area and simulate the change due to regulation of the area in the time.
