摘要
设计了河道淹没的三维仿真方案,利用历史水文数据,建立了水位-面积-容积模型。在该模型的基础上,分别通过时间和空间两个维度切片将历史水位数据进行插值,形成逐帧动画缓存,基于三维地形仿真平台,将连续洪水淹没过程嵌入虚拟地形中进行展示。该方案实现了符合历史规律的河道洪水淹没三维仿真。
In this paper, a three dimensional simulation of river channel is designed. Using the historical hydrological data, a water level- area- volume model is established. Basedon the model, the historical water level data is interpolated through two dimensions which istime and space, so that frame by frame animation cache can be formed. Basedon the three dimensional platform, the flood - inundated process can be appeared. The river flood - inundation simulation conformed to the law of history is realized by the scheme.
