| 摘 要： | 洪水演进仿真环境的绘制包括三维地形建模和地形地貌实时绘制,源发型洪水演进动态仿真技术的关键是流域河道边界自搜索模型的建立。采用广度优先搜索和河道自适应控制为主体算法,以Visu-al C 6.0为开发平台、OpenGL为图形编程接口,并以湖域水位上涨过程为例,开发了基于三维地形景观的源发型洪水演进仿真系统。动态过程仿真实验逼真地模拟了湖水水位抬升过程中湖盆内水位上涨和湖盆出口处湖水溢出的过程及湖水溢出湖盆出口后沿河道由高向低的流向。

| Abstract: | The rendering of flood evolvement simulate system includes 3D landform modeling and real-time rendering to landform and physiognomy.The key technology of the dynamic simulate of the original flood evolvement is the design of the self-control search model of the boundary of the watercourse's drainage area.Using the breadth-first search(BFS) and the watercourse self-control search(WSS) as primary arithmetic,visual C 6.0 as platform and OpenGL as graphics program interface,and taking the process of lake water level rise for example,an original-flood evolvement simulate system based on the 3D landform sight is developed.The dynamic system can simulate the process of water level rise in lake basin and water overflow at the exit of lake basin during the period of water level of lake rising and boosting.Also it can simulate the flowing direction of water along watercourse after it overflows the exit of a lake basin. |
