基于带参IFS的3D分形树及其摇曳形态的实现

3D Fractal Tree at Swing Based on IFS inline Parameters

首先阐述了带参IFS理论并分析了自然界中在风中树的摇曳形态,根据IFS理论定义了3D分形树的一般形式,然后确定仿射矩阵和参数,最后给出了一个四叉树的IFS码,并绘制了此3D分形树在风中摇曳形态,并提出了此算法的优点和不足。

This paper firstly discusses original IFS inline parameter, analyzes the shape of the tree in wind, based on IFS theory, gives a definition of a 3D fractal tree, then confirms the affine matrixes and parameters, finally gives the IFS code of a four-branch tree, and draws a 3D tree at swing.
