中文摘要：
实现热带风暴场景的模拟对于灾害预防、评估等工作具有十分重要的意义。改进了一种基于图像色彩和灰度值的算法，能够较好地从卫星云图中分割提取出热带风暴的云层区域，进而利用一定规则生成了云区体数据。针对生成体数据的特点，采用了一种改进的快速光线投射算法来完成热带风暴云区的三维绘制，最终实现了对于云区的任意角度实时观察和动态绘制。
英文摘要：
It is of much significance for disaster forecasting and evaluating to do the research of the tropical storm simulation. For the satellite images, the cloud regions of tropical storm are analyzed and segmented by an improved algorithm based on the color value and gray scale, and then the clouds volume data is generated. An accelerated ray-casting algorithm based on the coherence of the 3D data field is utilized on the tropical storm clouds visualization. Finally, the tropical storm clouds is viewed from any perspective angle and an animation method is Drooosed.
