递归分形树的形成，利用递归算法生成分叉树，将这个生成元在每一个层次上不断重画-Recursive fractal tree formation, the use of recursive algorithm to generate bifurcation tree, will the generator on at every level constantly re-draw

fractal generator. program draw on a screen one of the most simole fractal.

it is a fractal tree generator-it is a fractal tree generator..

可应用于分形计算，生成分形几何，有两种方式：（1）生成三种预定义几何的一种；（2）一般使用方法。(fractal computation software. Function to generate fractal geometries. % Works in two ways: 1) Generation of one of the three % predefined geometries or 2) general use, where axiom % and generator
