Real-time Simulation of Dynamic Cloud Based on Fractal

Cloud is a common, widespread natural phenomenon. Cloud modeling and rendering plays a great important role in virtual environments. This article based on texture splatting on particles method, and considers the clouds as a grade model. A method based on fractal is chosen to generate cloud texture and then texture is mapping to the facets. The method introduced in this article is simple and can improve the cloud modeling velocity. The results show that the method can meet the common requirements in scene simulation and have a good performance in real-time and reality.
