摘要
在分析IFS构建方法后,运用几何方法给出一类用多项式表示的非线性变换形式,并构造迭代函数系统,利用该方法构造的迭代函数系统绘制一些IFS的吸引子分形图进行实验.结果表明,非线性变换构造的迭代函数系统是仿射变换构造的迭代函数系统的一种延伸,该变换构造的IFS可以获得更加生动多样的IFS吸引子分形图.研究此类迭代函数系统可以为非线性交互式分形造型生成算法的研究提供一定的参考依据.
After analyzing the construction method of IFS,a class of nonlinear transformation expressed in term of polynomial was given by means of geometric approach and the iterative function system was constructed.By using this system,some IFS fractal diagrams of attractors were drawn and tested.The result showed that the iterative function system constructed in this way would be a kind of extension of the IFS constructed with mapping approach,and the images were produced more elaborately and diversified.The research on this kind of IFS would provide a certain basis for the interactive fractal modeling algorithm of nonlinear iterative function system.
