| Abstract: |
| In this paper the influence on the fractal graphics with the change of iteration function system(IFS)parameters was studied respectively.An efficient algorithm for designing IFS codes based on collage method was proposed and the strategies for regulating fractal graphics were summarized.Lastly, a strategy for adjusting IFS codes was presented, which was able to imitate the changes of branch bending and density of the leaves caused by wind and illumination during the plant growth process. |
