Study Of Base On Fractal Natural Scenery Simulation And IFS Information Extraction

The paper studies:1 .There are two methods for natural scenery simulation, L-system method and IPS system method ,making a comparison between the two methods, and implementing 3D scenery fractal generation by means of the visualizing program.2.This paper discusses deeply the scenery structure shape, dynamic generated process in accordance with the characteristics of simple generated law and complicated practice process of L-system . Since the hierarchical Traverse calculation is used, the practice process will greatly be simplified, the information transmission speed will be increased, and the information storage will be reduced.3.This paper studies the extracting fractal geometry objet from natural scenery graphics. For IPS system. On the one hand , the information code is extracted by adopting the alternating conventional method , on the other hand , a new extracting method, triangle method , is put forward on the base of conventional method. The practice process and principle of the two information extraction methods are introduced by analyzing the typical graphic examples. The triangle method is faster and less distorted than the conventional method through comparing their characteristics. Therefore ,the natural scenery simulated is more similar to the real object by the triangle method.
