摘要:
研究了迭代函数系统(IFS)的各个参数对生成分形图形的影响,在拼贴方法基础上提出了一种设计IFS码的高效方法,总结了调整分形图形的策略,对IFS码作微小调整,模拟植物生长过程中由风力、光照等因素引起的树枝弯曲程度和树叶疏密的变化。

Abstract:
In this paper the influence on the fractal graphics with the change of iteration function system(IFS)parameters was studied respectively.An efficient algorithm for designing IFS codes based on collage method was proposed and the strategies for regulating fractal graphics were summarized.Lastly, a strategy for adjusting IFS codes was presented, which was able to imitate the changes of branch bending and density of the leaves caused by wind and illumination during the plant growth process.
