摘要
对OpenGL这一性能卓越的三维图形开发平台的基本绘制原理作了简单介绍 ,论述了基于OpenGL的VisualC ++面向对象软件设计思想 ,着重阐明了以气象雷达终端原始回波数据为数据源的三维成像的数据处理、气象算法、实体建模、图像管理、用户交互等技术的应用以及具体软件实现中各层次结构的相互作用关系 ,实现了气像雷达降水回波三维图形的成像、剖切、旋转等功能 ,并给出了软件生成产品的三维图象应用实例 ,为今后气象分析提供了一种可视化程度高的方法。
Introduces the excellent OpenGL software development platform briefly, discusses the object-oriented Visual C++ software designidea which is based on OpenGL and clarifies the techniques of data processing, weather arithmetic, modeling, image management, interation as well as relationship of hierarchyies in the software. The functions of imaging, edging and rotation for 3D image of the data volume of precipitation echoes are achieved. The paper also provides some application examples of 3D image. From these, we can get a new visual tool for weather analysis.
