中文摘要:
   针对气象数据可视化应用中对渲染速度和出图质量的要求,基于抽象工厂模式设计并实现了一款集多种图形渲染技术于一体的渲染引擎。通过实时切换图形渲染技术,该引擎在保持图形显示属性不变的前提下,既能够提供由硬件加速技术所享有的高性能,又能够输出高质量的矢量图形。使用该引擎的气象信息分析处理系统能够实现天气图的交互制作,海量气象数据的实时显示,用于科研论文和业务演示的矢量格式图像文件生成。因此,该绘图引擎能够较好地满足天气预报业务和气象科研两个方面的可视化需求。
英文摘要:
   In response to the requirements for rendering performance and high imagery export quality in meteorological data visualization, a multifunctional graphics rendering engine is designed and implemented using abstract factory pattern. By switching the built-in rendering technologies from one to another on the fly while preserving the display properties of the graphics objects, the engine not only enjoys high performance thanks to hardware acceleration technology, but also exports high-quality vector images. The proposed engine has been incorporated into a meteorological information analysis and processing system, which can be used for interactive composition of synoptic chart, real-time visualization of large volume data, and automatic generation of vector-based figures used for publications and presentations. In all, the engine provides versatile features required in both meteorological operations and scientific research.
