| 摘 要： | 基于L系统的树的建模方法是一种基于符号的重写系统,它是一种常见树木建模方法,但是由此生成的树的模型相对简单,缺乏对树枝的粗细、分叉角度等细节信息进行有效进行控制,真实感不够强.文章提出一种基于L系统的树的改进建模方法,在模型构建过程中,对树枝的粗细度、长度以及分叉角度等细节信息进行控制,并拓展到三维空间,实现了三维树模型的真实感绘制.

| Abstract: | The method of tree simulation based on the L-system is a rewriting system based on the characters,which is a common method for modelling trees.However,the trees simulated by the L-system are too simple,lacking efficient controls on the thickness,branch angle and so on.This paper proposes an improved method of modeling trees based on the L-system.In the simulation of the trees,some controls are made on the details,such as the thickness of the branches,the angle of the branches and the length of the branches ... |
