VS配置OpenGL开发环境：GLFW库和GLAD库的配置

**1.去GLFW官网下载相应版本的配置文件：[点击打开链接][Link 1]，无论你的系统是32位还是64位，都建议下载32位的配置文件，如下图：**

**去GLAD在线服务获得glad.h配置文件[点击打开链接][Link 2]，按照下图的信息填写，获得glad.zip文件：**

**2.将下载的文件解压，得到VS各个版本的配置库，你可以根据你安装的VS版本选择，由于笔者安装的是VS2013，所以选择lib-vc2013，在解压好的文件里面，我们只需要两个文件夹里的东西：include里面的GLFW文件夹和lib-vc2013；解压glad.zip后可以看到两个文件夹：include和src，我们将include文件夹里面的KHR和glad文件夹考到新建文件夹include里面，如下图所示：**

**再将lib-vc2013文件夹和include文件夹放同一文件夹下，如下图：**

**好到这里文件夹整理工作完毕，接下来看如何配置！！！**

**3.将lib-vc2013文件夹里的glfw3.dll文件复制到系统文件夹里面：C:\\Windows\\System32和C:\\Windows\\SysWOW64。**

**4.打开VS2013，新建一个控制台应用程序，新建一个demo.cpp，并将glad.zip解压得到的src文件夹里面的glad.c添加到项目中，如下图所示：**

**5.链接包含目录和库目录，右键单击解决方案：属性->配置属性\->VC\++目录：将步骤2里面的两个文件夹路径包含进来，如下图：**

**6.链接库：opengl32.lib和glfw3.lib。右键单击解决方案：属性->配置属性->链接器->附加依赖项，如下图：**

**到这里，配置大功告成，下面进行第一个例子的运行！！！**

7.实现一个OpenGL窗口：hello window。

**demo.cpp代码：**

#include <glad\glad.h>
    #include <GLFW\glfw3.h>
    
    #include <iostream>
    void framebuffer_size_callback(GLFWwindow* window, int width, int height);
    void processInput(GLFWwindow *window);
    
    // settings
    const unsigned int SCR_WIDTH = 800;
    const unsigned int SCR_HEIGHT = 600;
    
    int main()
    {
    	// glfw: initialize and configure
    	// ------------------------------
    	glfwInit();
    	glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    	glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    	glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    
    #ifdef __APPLE__
    	glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE); // uncomment this statement to fix compilation on OS X
    #endif
    
    	// glfw window creation
    	// --------------------
    	GLFWwindow* window = glfwCreateWindow(SCR_WIDTH, SCR_HEIGHT, "LearnOpenGL", NULL, NULL);
    	if (window == NULL)
    	{
    		std::cout << "Failed to create GLFW window" << std::endl;
    		glfwTerminate();
    		return -1;
    	}
    	glfwMakeContextCurrent(window);
    	glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);
    
    	// glad: load all OpenGL function pointers
    	// ---------------------------------------
    	if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
    	{
    		std::cout << "Failed to initialize GLAD" << std::endl;
    		return -1;
    	}
    
    	// render loop
    	// -----------
    	while (!glfwWindowShouldClose(window))
    	{
    		// input
    		// -----
    		processInput(window);
    
    		// glfw: swap buffers and poll IO events (keys pressed/released, mouse moved etc.)
    		// -------------------------------------------------------------------------------
    		glfwSwapBuffers(window);
    		glfwPollEvents();
    	}
    
    	// glfw: terminate, clearing all previously allocated GLFW resources.
    	// ------------------------------------------------------------------
    	glfwTerminate();
    	return 0;
    }
    
    // process all input: query GLFW whether relevant keys are pressed/released this frame and react accordingly
    // ---------------------------------------------------------------------------------------------------------
    void processInput(GLFWwindow *window)
    {
    	if (glfwGetKey(window, GLFW_KEY_ESCAPE) == GLFW_PRESS)
    		glfwSetWindowShouldClose(window, true);
    }
    
    // glfw: whenever the window size changed (by OS or user resize) this callback function executes
    // ---------------------------------------------------------------------------------------------
    void framebuffer_size_callback(GLFWwindow* window, int width, int height)
    {
    	// make sure the viewport matches the new window dimensions; note that width and 
    	// height will be significantly larger than specified on retina displays.
    	glViewport(0, 0, width, height);
    }

**运行结果：**
