基于迭代函数系统的森林景物的动态模拟技术的研究

The Studies of Dynamic Approach Method of Forest Scenery Based on Iterated Function System(IFS)

文章给出了一种基于迭代函数系统IFS的森林景物的动态模拟方法。首先介绍了以迭代函数系统来探索和解决森林树木这一类自然景物的计算机生成问题的途径,然后从一个已模拟景物的IFS吸引子出发,改变参数自动生成无重复的序列画面,以此达到对森林景物动态模拟的目的。用此方法生成的前后两帧图形之间既有区别,又具有相对的连续性。为计算机动画对复杂的自然景物的动态模拟提供了一条新的途径。

This paper introduces the dynamic approach method of forest scenery ba se d on iterated function system(IFS).Firstly,it shows the studies of computer graphics generation problem of trees and forests by iterated function system(I FS),then many computer graphics of no mechanical looking are generated by chan ging the IFS attactorin order to dynamically approch forest scenery.There is di fference between two graphics generated by the method but they is successive. The method gives a new study of dynamic approach for complex natural scenery.
