一个OpenGL ES 的简单使用例子代码

这是一个OpenGL ES 的简单使用例子代码（主要是初始化部分），这些代码不能简单C/V到你的工程中，因为他不是完整的可运行代码。

另外，目前能够用在v1.1一

// ----------------------------------------------------------------------

// Initialization

// ----------------------------------------------------------------------

HDC hdc = GetDC(0); // the screen or window device context, for example

EGLDisplay display = eglGetDisplay(hdc);

EGLint major, minor;

if (!eglInitialize(display, &major, &minor)) {

// could not initialize display

}

EGLConfig configs[10];

EGLint matchingConfigs;

EGLint attribList[] = { 0 }; // extend this

if (!eglChooseConfig(display, attribList, &configs, 10, &matchingConfigs)) {

// could not choose config

}

if (matchingConfigs < 1) {

// did not find a suitable configuration

}

EGLConfig config = configs[0]; // pick any

EGLSurface surface = eglCreatePbufferSurface(display, config, attribList);

// test for error

EGLContext context = eglCreateContext(display, config, 0, attribList);

// test for error

// ----------------------------------------------------------------------

// Rendering Loop

// ----------------------------------------------------------------------

eglMakeCurrent(display, surface, surface, context);

// actual GL rendering goes here

eglWait();

eglSwapBuffers(display, surface);

// ----------------------------------------------------------------------

// Cleanup

// ----------------------------------------------------------------------

if (!eglDestoyContext(display, context)) {

// error deallocating context

}

if (!eglDestroySurface(display, surface)) {

// error deallocating surface

}

if (!eglTerminate(display)) {

// error while cleaning up display

}
