说明：  依据分形迭代函数系统(工FS)生成了Sierpinski三角形、Sierpinski金字塔、 分形树等各种分形图。讨论了几种基于IFS的彩色树木的模拟技术，并研究了迭 代过程中随机因素和吸引子对色彩植物模拟的影响
(Based on fractal Iterated Function System (Works FS) to generate the Sierpinski triangle, Sierpinski pyramid, fractal tree and other fractals. Discussed several of the color of trees based on the IFS simulation technology, and studied the iterative process of random factors and the attractor plant simulation of the impact of color)
