摘要
给出了一个适用于水利领域的三维可视化系统的组成,介绍了解决超大数据量数字高程模型(DEM)快速显示的算法,将地物在地形中进行显示,研究了基于三维场景空间分析的理论,最后对系统的实现作了简要介绍。实践表明该系统能在PC机上流畅地运行,图形的生成速度和质量令人满意。
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.
