Abstract: This paper summarizes three fractal methods used in Computer Graphics, Random fractal method, Nonrandom fractal method and IPS method, and clarifies how to use them to generate geometric graphics and scenic images. We have completed the whole process of IFS method, t Experiment} results of each method are presented, a nature scenic image is generated by fractal methods only.
