这是一个Android上的OpenGL ES 2.0 学习工程，我会不断地补充sample，并在关键代码处附上中英文注释。

This is a OpenGL 2.0 learning project for Android, and I will continue to code and commit samples and write chinese and english commets for some import code.

在我的掘金上，我会发布相关的Android OpenGL ES 2.0教学文章，包括每个例子的对应的讲解文章，以及一些其它知识，欢迎关注：https://juejin.im/user/5afabe81f265da0b7b361036/posts

I will publish some Android OpenGL ES 2.0 learning articles on my juejin, including the articles related to every samples in this project, and other knowledge. Welcome! Link: https://juejin.im/user/5afabe81f265da0b7b361036/posts

目前工程中有6个例子:
