| 摘 要： | 基于数学模型的洪水演进计算输出结果通常表达为数值表示的水位流速场，为了探寻洪水演进的规律，借助可视化的手段将数据进行了基于图像图形的直观表达；同时以虚拟现实平台软件Vega Prime为基础，分析了实现流场动态可视化的技术框架、实现方法，并通过实例对该方法进行了验证。结果表明，该方法能较好地实现流场的可视化表现，可用于超大流量天然河道洪水演进模拟。

| Abstract: | The calculated result of flood routing based on mathematical model is usually expressed in numerical values which indicate water level and flow velocity field. In order to discover the regularity of flood progression,visualization tools are used to make values be expressed impressively by graphics. In this paper,the dynamic visualization of flood is based on Vega Prime software which is a virtual reality platform. Technical framework and realization of methods about dynamic visualization are researched and ... |
