| 摘 要： | 洪水演进仿真系统的研制，是实施“数字流域”工程的重要组成部分；结合洪水演进可视化目标的分析，基于Visual C 系统开发平台，融GIS技术和Opengl开发技术，采用三角形逼近、光滑处理和加入法向量以控制光照的方式，实现了流域地形及河床的三维可视化仿真；应用广度优先搜索算法确定了运动水体与流域河床形态的自适应与自相依的关系，使流域洪水演进模拟具有真实自然的可视化效果。所研制的系统雏形，可有效的模拟流域洪水的三维演进过程；

| Abstract: | The study and development of flood routing simulation system is an important component of "digital valley" engineering. According to the analysis of flood routing visualization aim, three-dimensional simulation of valley's terrain and riverbed is realized, based on visual c programming platform, integrating GIS and OpenGL technology, applying triangular mesh, smooth processing and normal vector to control manner of illumination. The system can materialize the relation of self-adapting and dependence between flood and riverbed with breadth-first search arithmetic, and visual effect of flood routing is more natural. This rudimental system can simulate the course of flood routing effectively. |
