# OpenGL-ES-2.0-cpp
---------------------
# Introduction
This is a graphics application based on OpenGL ES 2.0 API, using C++ and the OpenGL ES Shading Language. The logic structure of this project is like the cocos2d-x game engine, it is started by main.cpp which contains main() function and calls Appdelegate's run() function.
Main contents in this project are:
## Draw Rectangle， Circle， etc , simple graphics.
these simple graphics drawwing programs help understanding the process of a OpenGL ES program running.
## Texture
- basic texture rendering
- multiple texture rendering
## Mipmapping
## 3D projection
## Using of buffer objects: VAO, VBO
## Alpha test, depth test
# [ ] Critical Codes
```c++
namespace elloop {
class Application; // application abstraction.
class AppDelegate; // derived from Application.
class OpenGLView; // Windows control and OpenGL ES Drawing Context.
class Director; // control the process of rendering.
class Drawable; // things to be rendered.
class Ref; // Object, for reference counting.
class AutoReleasePool; // manage the reference count of pointer to object of type Ref.
class PoolManager; // manage AutoReleasePool stack.
// ShaderHelper: help class for compiling and linking shader programs
class ShaderHelper {
public:
static const ShaderId compileVertexShader(const std::string &shaderSrc);
static const ShaderId compileFragmentShader(const std::string &shaderSrc);
static ProgramId linkProgram(ShaderId vertexShaderId, ShaderId fragShaderId);
private:
static ShaderId compileShader(const std::string &shaderSrc, GLenum shaderType);
};
}
```

=============================
# 中文文档
这个项目是一个基于OpenGL ES 2.0 API的图形演示程序，编程语言是C++和The OpenGL ES Shading Language. 工程的逻辑架构是模仿cocos2d-x来组织的，main函数在main.cpp里面，其中启动Appdelegate来完成程序的启动。
主要包含的内容有：
## 绘制矩形，圆等简单图形
## 绘制纹理
## Mipmapping
## 3D投影
## 使用缓冲对象：VAO，VBO
## Alpha测试 深度测试
