A point-based hybrid cloud modeling technique

A hybrid approach to cloud modeling and shading based on volumetric procedural modeling, particle modeling and point primitives is proposed in this work. The volumetric procedural modeling allows great flexibility in controlling object's level of detail, the particle modeling enables to model clouds piece by piece to facilitate interactive fly-in animation, and the point primitive facilitates the multi-resolution representation and animation of complex objects. A preliminary experimental result is given to demonstrate the superior performance of the proposed method.
