-repo Initial Construction Instructions:
-
-The project was set up for 3 target
-
-	1. To help cmgameengine a completely new renderer
-	2. In order to need to learn OpenGL Core/ES friends to provide a follow-up learning process
-	3. Provide a least dependent renderer for friends who simply need to learn game making

-仓库初建说明：
-
-	设立这个项目有3个目的
-
-	1.为了帮助CMGameEngine重新一个全新的渲染器
-	2.为了需要学习OpenGL Core/ES的朋友提供一个跟随学习的过程
-	3.为仅仅需要学习游戏制作的朋友提供一个最少依赖的渲染器

-1.ULRE是CMGameEngine的渲染器试验原型项目，所以它们是有关系的
-2.两者的代码是互相借鉴的
-3.ULRE仅用于试验渲染技术，所以它不会在渲染以外的地方使用任何技巧，也不考虑任何实际使用情况。

-1.ULRE is a renderer prototype project for CMGameEngine, so they are related
-2.The code of the two is borrowed from each other.
-3.ULRE is only used to experiment with rendering techniques, so it doesn't use any tricks outside of rendering, nor does it take into account any actual usage.
