摘要
针对不规则物体的造型特点，笔者首先分析分形的基本生成方法之-L系统的基本作图原理，改进了一种基于L系统的三维分形树的算法，然后讨论当前典型的分形山的生成方法中点位移法，并对上述两个算法进行了计算机模拟．
According to the characteristic of plastic method of abnormal object, this paper analyses the principle of L system which is a method of fractal theory at first, improves a generation algorithm of 3 D fractal tree based on L system and then discusses the midpoint displacement algorithm to create the fractal mountain and imolements the algorithm above.
