Generation of Koch Curve with Unitary Regulation of L System and Its Applications

In this paper, the classical fractal graph - Koch curve was generated with unitary regulation of L system in visual C++, and the regular fractal graphs, fractal trees and handkerchief curves which have typical fractal characteristics were generated by changing the elements of generation. The unitary regulation of L system is intuitively expressed by computer language, it can not only help to understand the program design ideas, but also appreciate the way of fractal generation and the basic principles and features of fractal, for profound exploring the rules in process of fractal generation has certain research value. Generated fractal graphs can also be applied to the design field.
