L系统在植物形态模拟中的应用

植物是自然界的重要组成部分.随着分形理论的研究与发展,虚拟植物已经成为计算机图形学研究的热点问题.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.为此,论述了L系统的基本概念,并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;考虑了植物的趋光性、向地性等生长特性,将扰动变量和随机性引入了L系统,使生成的植物图像更加贴近自然,提高了植物图像的逼真性.

Application of L-system in Plant Simulation

With the development of fractal, virtual plant has been a very interesting problem in computer graphics. For its simple definition and highly structurization, L-system has been one of the most common methods in plant simulation. This paper introduced the basic concept and expressive principle of L-system, and modeled plants by using computer. Considered some growth characters of plants such as photokinesis and geotropism, disturbancy variable and randomness were introduced into L-system in order to create more natural and more living image.
