Abstract: Based on the basic idea of particle system that the individual behavior is controled by groups behavior, an improved simulation algorithm for "Bamboo" distributional pattern was presented. In this paper, the improved simulation algorithm makes the random distribution of particles to break the rules of rectangular shape. Then, the improved algorithm can simulate different "Bamboo" distributional pattern more really. This paper gave a new solution in plant simulation and made the particle system to be applied in the plant growth pattern.

Key words: Improved particle system, "Bamboo" distributional pattern, Simulation algorithm
