| Abstract: | Introduces the complement of simulation of driving water from ChangJiang to Taihu system,that is a 3D visualization system used to the water conservancy.And the technology of how to display huge volume of digital elevation model(DEM) data is introduced,and spatial analysis is studied based on the terrain created using DEM.In the end,the paper introduces the process of the implementation in brief.The practice improved that this system can run well in PC with satisfied speed and quality to generate graphics. |
