IFS分形图像的组合随机数算法

Combined Random Numbers Algorithm of IFS Fractal Images

设计了性能优异的组合随机数序列发生器,通过偏差算子的作用得到取值范围可调的随机数序列,对仿射变换参数系统进行随机调整,控制迭代函数系统(IFS)分形图像的形态变化.以自然景物的树木生长为研究实例,应用计算机图形技术随机生成形态变化多端的树木.实验结果表明,该方法能较好地模拟自然界的一些景象.

A combined random number generator of excellent capability is adjusted. The various kinds of random numbers sequence can be gained by the warp operator. Furthermore, in order to control the shape of Iterated Function System （IFS） fractal images, the parameter of affine transform system are changed. Finally, the effects of the methods are showed by computer mathematics experiments in the simulation of the tree. The results indicate that the algorithm is simple and easy to be realized.
