基于红外卫星云图的云的三维表现

3D Visualization of Cloud Based on Infrared Nephogram of Satellite

分析红外卫星云图结构特点,阐明其三维化原理。借鉴LOD思想,利用多种采样间隔获得不同精度数据网格。根据云团真实感效果制定颜色及透明度映射规则。结合三维地形可视化方法,设计并实现了红外卫星云图的三维可视化。

Analyze the configurative character of infrared nephogram of satellite, and then clarify its theory of 3D visualization. Using the idea of LeD for reference, obtain diverse data grids of various precisions by different sampling intervals. According to the reality impression of cloud, establish rules of color and diaphaneity mapping. Integrated with the method of terrain＇ s 3D visualization, design and realize the 3D visualization of infrared nephogram of satellite.
