| Abstract: | Satellite cloud image is one of the most important sources of the weather information, and it is of much significance for disaster forecasting and evaluating to do the research of satellite cloud image simulation. The framework of the open-source platform WorldWind was discussed. For the satellite images, the cloud regions were analyzed and segmented by an improved algorithm based on the color value and gray scale. The multilayer texture mapping algorithm was utilized on satellite cloud image simulation, and the procession was integrated to the open-source platform WorldWind. |
