摘要: 为满足三维分形图形的描述要求,在传统L-系统的基础上提出一种新的三维分形图形描述语言系统——E-L系统。该系统对L-系统的符号进行扩展,以便更好地支持三维分形图形的描述,增加随机参数,使分形图形更加真实,限定符号的类型,使其表达方式更加通用。设计一种三维分形图形的形态控制方法,克服传统分形图形最终形态无法控制的缺点。实验结果表明,E-L系统可以较好地描述具有自相似性的三维分形图形。

Abstract: In order to meet the requirement of three-dimensional fractal graphics description, this paper proposes a new three-dimensional fractal graphics description language system called E-L system on the basis of the traditional L-system. In E-L system, the traditional symbols of L-system are expanded to support three-dimensional fractal graphics description. The intrinsic randomness is added to the symbol for more reality fractal graphics. The type and form of symbol is limited for providing a more convenient way to express vary acts. A three-dimensional fractal graphics morphology control way is designed to overcome the shortcoming of the traditional final fractal graphics which is always beyond control. Experimental result shows that the E-L system has a very good description capability for self-similar three-dimensional fractal graphics.

Key words: L-system, three-dimensional fractal, graphic description, E-L system
