基于改进分形L系统植物自然现象的研究

植物是自然界的重要组成部分,虚拟植物的研究为探索植物生命的奥秘和生长过程的规律,以及改善人类生存环境质量带来了新的契机,因此它已经成为计算机图形学研究的热点问题,由于植物经常受到外界环境因素的影响,因此在论述了L系统的基本概念的基础上对现有的L系统进行改进使之在结合外界环境影响作用下对植物进行模拟,首先提出了植干粗细的两种解决办法,其次对树木受自然环境影响而产生的重要现象如顶端优势,趋光性和蠲地性,以及风力因子等因素进行了模拟,最后用IFS算法模拟植物具有纹理的组成部分,模拟实验表明,改进的L系统可以比较逼真地模拟植物在自然环境中的形态.

Research on Nature Plant Based on Improved L-System

All research of the virtual plant will bring a new chance for investigating the profound mystery of the plant life and the regulation of the growth processes and improving mankind's existing environment,so virtual plant has been a very interesting problem in computer graphics, and environment is a key factor affecting the development of plants.So this paper introduces the basic concept of L-system,and improves the L-system to simulate plant in nature.At first the paper proposes two ways to improve the width...
