使用glew和glfw进行opengl编程

freeglut和glut是很多教程使用的,不过现在glfw明显好多了,还有glew是windows下面使用opengl1.1以上版本api的比较好的办法,更重要的是这两个都是跨平台的,用起来真的是很方便的说,

#define GLEW_STATIC
#include 
#include 
#include 
#include 

char szTitle[64] = "opengl tutorial 001-color triangle";

static void error_callback(int error, const char* description)
{
    fputs(description, stderr);
}

static void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods)
{
    if (key == GLFW_KEY_ESCAPE && action == GLFW_PRESS)
        glfwSetWindowShouldClose(window, GL_TRUE);
}

int main(void)
{
    GLFWwindow * window;

    glfwSetErrorCallback(error_callback);

    if (!glfwInit()) return -1;
    window = glfwCreateWindow(512,400,szTitle,NULL,NULL);
    if (!window)
    {
        glfwTerminate();
        exit(EXIT_FAILURE);
    }

    glfwMakeContextCurrent(window);

    glfwSetKeyCallback(window, key_callback);

    glewExperimental = GL_TRUE;
    glewInit();

    while (!glfwWindowShouldClose(window))
    {
        float ratio;
        int width, height;

        glfwGetFramebufferSize(window, &width, &height);
        ratio = width / (float) height;

        glViewport(0, 0, width, height);
        glClear(GL_COLOR_BUFFER_BIT);

        glMatrixMode(GL_PROJECTION);
        glLoadIdentity();
        glOrtho(-ratio, ratio, -1.f, 1.f, 1.f, -1.f);
        glMatrixMode(GL_MODELVIEW);

        glLoadIdentity();
        glRotatef((float) glfwGetTime() * 50.f, 1.f, 0.f, 0.f);

        glBegin(GL_TRIANGLES);
        glColor3f(1.f, 0.f, 0.f);
        glVertex3f(-0.6f, -0.4f, 0.f);
        glColor3f(0.f, 1.f, 0.f);
        glVertex3f(0.6f, -0.4f, 0.f);
        glColor3f(0.f, 0.f, 1.f);
        glVertex3f(0.f, 0.6f, 0.f);
        glEnd();

        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    glfwDestroyWindow(window);

    glfwTerminate();
    return 0;
}

简单的一个例子
