three实现可交互三维毕达哥拉斯树（Pythagoras Tree）效果代码-html代码-BFW代码库

代码语言：html

所属分类：三维

代码描述：three实现可交互三维毕达哥拉斯树（Pythagoras Tree）效果代码，毕达哥拉斯树（Pythagoras Tree）是一种分形图形，由荷兰数学家Albert E. Bosman于1942年创造。这个图形是基于毕达哥拉斯定理（即直角三角形中，斜边的平方等于两直角边的平方和）的几何构造。毕达哥拉斯树的基本构造步骤如下：从一个正方形开始，这个正方形被称为“树干”。在正方形的上方，构造一个直角三角形，使得正方形的顶边是直角三角形的一条直角边。在直角三角形的两条直角边上分别构造两个新的正方
