面向地学过程的计算可视化研究——以洪水演进模拟为例
DOI: 10.11821/xb20027s006, PP. 37-43
Keywords: 计算可视化,地理信息系统,地学过程,洪水模拟,引导计算,实时互动
Abstract:
在对包含过程事件的地理系统进行分析的基础上，区分并定义地理系统动态变化中的两类对象基座对象和事件对象，并对两类对象的特征，进行了讨论。依据两类对象的划分，探讨了基座对象数据模型和事件对象数据模型的特征，并从人与模型计算、人与三维图形图象的实时互动要求，提出建立视景数据模型的必要性，并说明对象数据模型和视景数据模型的相互关系。在此基础上，对计算可视化环境系统进行了框架设计，并应用VisualC++和OpenGL，自行开发了一个原型系统GeoVision，以洪水演进模型的计算与可视化为案例，进行了初步试验。
