Abstract: Computer simulation of snow crystal growing process has been done for many years. Cellular automaton is a computing model which is made from lattice cells and simple rules. Though it is a very simple model, it gives good results when used to imitate complex processes such as the life phenomenon, crystal growth and the turbulent flow. In this paper, a cellular model for 3Dimensional snow crystallization was proposed by extending the traditional 2Dimensional cellular model. Simulation results indicated that the proposed model can accurately simulate most 3Dimensional snow crystallization processes.
