Abstract: This paper established the model of clouds based on cellular automata and developed the method of how to deal with boundary grid points.It also described some of the dynamic aspects of clouds by using promoted transition rules and introduced ascending air current.These techniques enhance the run-time efficiency.At the same time,it used multiple forward scattering model in illumination calculation and embedded Henyey-Greenstein phase function into forward scattering.The simulation results show that the proposed methods can implement real-time rendering of the clouds realistically.

Key words: Real-time rendering,Cellular automata,Dynamic clouds,Multiple forward scattering
