摘要
基于迭代函数系统(IFS)理论研究了二维自然景物的计算机建模技术。讨论了传统的IFS拼贴建模方法,从整体和局部的组合与相似关系出发,对传统拼贴建模方法进行简化,给出两种简化方法:局部轮廓法和三点法,分析了3种建模方法的应用条件和具体实现技术。最后,通过典型图例的实验,对3种建模方法进行了比较。
This paper addresses the modeling for two-dimensional natural scenery based on iterated function system. Firstly, the traditional method of collage modeling is described. Then the part-outline method and three-points method are presented by simplifying the traditional method based on the similarity between the whole and parts. The applicability of all three methods is also analyzed. Finally, the advantages and shortcomings of these methods are concluded through the experiments of typical graphics instances.
