The modeling and rendering of clouds are difficult problems in computer graphics.In this paper,we study the simulation of clouds from the modeling method,lighting model and the rendering efficiency.We present a new modeling method which combines the Cellular Automaton method with the particle system method.Based on the analysis of the cloud's optics property and the single scattering model,we present a new simpler formula for the lighting model.In this article,we also improved the rendering efficiency of the cloud by using the LOD technology,stoppage ahead technology,the space segmentation technology and etc.In addition,there are some description about the implementation details of the above mentioned method.
