Fractal theories are quite popular in modeling and simulation of objects with irregular shapes. The combination of fractal theories and virtual reality technologies may be used to generate the realistic and complex nature objects. Plants simulation is one of the most important fields in computer graphics. The simulation algorithms of Bamboo are discussed. The conventional L-system modeling approach is improved based on the single-axis characteristics of Bamboo, and the relevant method, e.g. the displacement mapping technique used in Bamboo internodes modeling and rendering is discussed as well. Moreover, based on the basic idea of particle system, an improved simulation approach for distribution pattern of Bamboo is presented.This improved simulation algorithm can make the random distribution of particles break the rules of rectangular shape. Simulation results show that the proposed methods can simulate realistic Bamboo forms and distribution patterns in the nature.
