摘要
新一代天气雷达三维拼图产品显示系统是采用三维VTK(Visualization Toolkit)技术,结合具体的空间体绘制算法,开发的显示平台。此显示平台针对中国气象科学院国家灾害天气重点实验室开发的新一代天气雷达3D组网拼图产品,在兼顾实时处理和事后分析的需求下,实现了包括X,Y,Z平面在内的空间任一切面的雷达回波强度显示,运用光线投影算法实现了雷达回波数据的空间整体三维重建显示。同时结合多种产品的二维平面显示功能以及二维和三维的交互功能,更为直观和全面的展现了空间回波的分布状况,使得三维组网产品的优势在业务系统上得到更大程度的发挥。
The display system of weather radar 3D mosaic products, which combined with the Volume Rendering Algorithm is a displaying platform on VTK （Visualization Toolkit）. The platform aimed at weather radar 3D mosaic products, which is developed by State Key Laboratory of Severe Weather of Chinese Academy of Meteorological Sciences. By taking into account the demand of real-time processing and post-analysis, it realized the radar reflectivity display of any plane, including the X, Y, Z planes. Using ray-casting algorithm, it realized the three dimensional reconstruction of radar reflectivity. Combining with 2D display of products and interaction function of 2D and 3D, it comprehensively displayed the spatial distribution of the radar echo, and made the advantages of 3D mosaic products into full play.
