openGL程序 简单的程序叫你如何掌握用递归思想（L-system）画一棵树（有树干有叶子）。这也是画地形的必修课。-openGL program simple procedure called recursive thinking you how to master the (L-system) draw a tree (a tree with leaves). This is a required course terrain painting.

关于用L系统模拟3D植物的论文7篇，主要是关于植物枝干模拟和L系统的建立-L system on the use of 3D plant simulation paper 7, the main branches on the plant simulation and L system

基于opengl，花了一个雪人场景，还有L系统树，可以看看。(Based on OpenGL, a snowman scene and a L system tree can be seen.)
