Abstract: The quick development of the technique of virtual reality opens a ne w area for the theory of fractal. The paper analyzes the main methods of fractal simulation of the configuration of plants and points out their difficulties, pu ts forward a simplified algorithm of L-system based on VRML. The detailed method s by which VRML interacts with Java are discussed. By using the simplified algor ithm of L-System, examples of interactive 3D fractal trees are generated. At las t, the significance of the research is pointed out and a practical application i s given.
