三维嵌套L系统及其在植物模拟中的应用

随着分形理论研究的不断发展，虚拟植物已经成为计算机图形学研究的热点问题之一。其中，L系统以其定义的简洁性和高度的结构化特点，成为植物形态模拟中最常用的方法之一。在简要介绍其表达机制的基础上，利用计算机对植物的形态进行了模拟，提出了一种嵌套L系统，它采用过程化形式控制树木的形态，避开了去寻找L系统生成规则的难点，构造了椰子树的模型，从实验模拟结果看，嵌套L系统可以更逼真地反映植物的形态。

Three dimensional embedded L-system and its application in plant simulation

With the development of fractal research,virtual plant has become a hot and interesting research topic in computer graphics area.For its simple definition and highly structurization,L-system becomes one of the most common methods used in virtu- al plants simulation.This paper proposes a new method to solve the problem using embedded L-systems which can be used to con- trol the plant shape.The new method is then used to simulate coconut tree and thus avoid to finding the generation rules.The ex- perimental r...
