摘要
泥石流过程模拟的三维可视化不仅能改善泥石流过程信息的视觉效果， 更能有助于发现泥石流运动的宏观规律， 并为过程模拟数据的深层次分析奠定基础。分析了基于流团模型的泥石流过程模拟系统（ＤＥＢＲＩＳ）的数据结构和栅格式ＧＩＳ－ ＥＲＤＡＳ系统的数据结构，设计了ＤＥＢＲＩＳ与ＥＲＤＡＳ间的数据转换算法， 从而实现了两个系统间的可视化集成即基于地理信息系统（ＧＩＳ） 的泥石流过程模拟三维可视化。
The 3 D visualization of debris simulation can not only improve the representation of debris process,but also is very helpful for discoverying the macro rules controlling debris flowing and so can lay good foundation for providing later deeply analysing policy.In this paper,two systems are introduced.One is a system for debris simulation based on particle model(DEBRIS),developed by our department,the other is the well known RS GIS integrated raster GIS ERDAS.Based on detailed data structure analysis of both systems,a 3 D dynamic visualization policy is designed and realized.
