%X Cloud is a common, widespread natural phenomenon, cloud modeling and rending are a difficult problem in the field of computer graphics. I}his article used Repeat Texture Mapping to make up multiple 2D texture images for modeling 3D dynamic cloud, through the instantaneous translation of the cloud, zooming and other operations to simulate the dynamic changes of cloud, further used alpha color fusion technique to simulate dynamic cloud gather, dissipation and the cloud form changes after the effect of wind, by using the superposition of multilaycr repeat texture mapping to simulate the effect of layer cloud and obtain good simulation of the dynamic effect of cloud. The proposed modeling dynamic cloud method is simple, avoids a large number of tedious calculations, improves the speed of dynamic cloud generation and meets the animated scenarios for dynamic applications such as real-time requirements of cloud. I}he experimental resups validate the correctness of the proposed method of Dynamic Cloud Modeling and rendering generation.
