Research and Application of 3D Model for Real-time Dynamic Visualization Scheduling of Flood

为了满足大规模洪水演进过程的三维仿真需求,提出洪水实时动态可视化调度三维模型的研究,分析洪水风险评估,描述图形数据与属性信息空间实体。利用四叉树算法,分析面向灾害过程的虚拟场景,根据实时动态三维可视化流程,将参数信息传递到服务器端,借助动态调用和异步调用Web服务实现互操作。计算水流在方向上的动量方程,构建洪水实时动态可视化调度三维数学模型。实验结果表明,该模型洪水演进清晰度较高,为防洪方案实施提供技术支持。

In order to meet the needs of 3D simulation of large-scale flood routing process,the research on 3D model of real-time dynamic and visual flood dispatching is proposed.The flood risk assessment is analyzed and the spatial entities of graphic data and attri-bute information are described.Based on the real-time dynamic three-dimensional visualization process,the parameter informa-tion is transferred to the server side,and the interoperability is realized by dynamic and asynchronous call of Web services.The momentum equation of water flow in direction and momentum equation in direction are calculated,and the three-dimensional mathematical model of real-time dynamic and visual flood dispatching is constructed.The experimental results show that the model has high definition of flood routing and provides technical support for flood control scheme implementation.
