Windows10 OpenGL安装及配置

一、环境

Windows 10 64位家庭版
vs版本：Visual Studio 2017

二、配置OpenGL所需

GLFW
GLAD

三、步骤

　　1.配置GLFW

进入官网下载GLFW并解压：GLFW下载
这里选择32位的，因为64位的可能有些问题
进入VS2017创建空项目，在项目文件夹下创建includes和libs两个文件夹（如创建项目OpenGL，则为OpenGL/OpenGL/includes）
将解压文件中lib-vc2017文件夹下的.lib文件拷贝进刚刚创建的libs下，同时将include下的.h文件拷贝进刚刚创建的includes下
在项目名处右键->属性->VC++目录->引用目录->编辑：粘贴项目文件夹下的.h文件所在目录
同理，库目录->编辑：粘贴项目文件夹下的.lib文件所在目录
接着将为项目添加依赖项：仍然是属性->链接器->输入->附加依赖项->编辑，将opengl32.lib，glfw3.lib，msvcrt.lib添加进去

　　2.GLAD

进入GLAD官网：GLAD下载
Language选C\C++，Profile选core，version根据需要选择（3.3版本及以上），然后GRNERATE，之后选择zip文件下载并解压
将include下的.h文件全部拷贝进项目文件夹下的includes下，将src下的glad.c拷贝进项目文件夹下
然后进入vs，添加源文件->现有项，将glad.c添加进项目
至此库文件配置完成，接下来测试是否能正常使用OpenGL

　　3.测试OpenGL

创建源文件，首先需要引用glad.h和glfw3.h文件
因为使用的是自己添加的文件，这里引用需要使用“ “而非<>，使用” “时，它会自动出现你所添加的目录

  1 #include"includes/glad.h"
  2 
  3 #include"includes/glfw3.h"
  4 
  5 #include <iostream>
  6 
  7 void framebuffer_size_callback(GLFWwindow* window, int width, int height);
  8 
  9 void processInput(GLFWwindow *window); // settings
 10 
 11 const unsigned int SCR_WIDTH = 800;
 12 
 13 const unsigned int SCR_HEIGHT = 600;
 14 
 15 int main() {
 16 
 17     // glfw: initialize and configure
 18 
 19     // ------------------------------
 20 
 21     glfwInit();
 22 
 23     glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
 24 
 25     glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
 26 
 27     glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
 28 
 29 #ifdef __APPLE__ glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
 30 
 31     // uncomment this statement to fix compilation on OS X
 32 
 33 #endif
 34 
 35 // glfw window creation
 36 
 37 // --------------------
 38 
 39     GLFWwindow* window = glfwCreateWindow(SCR_WIDTH, SCR_HEIGHT, "LearnOpenGL", NULL, NULL);
 40 
 41     if (window == NULL)
 42 
 43     {
 44 
 45         std::cout << "Failed to create GLFW window" << std::endl; glfwTerminate(); return -1;
 46 
 47     }
 48 
 49     glfwMakeContextCurrent(window);
 50 
 51     glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);
 52 
 53     // glad: load all OpenGL function pointers
 54 
 55     // ---------------------------------------
 56 
 57     if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
 58 
 59     {
 60 
 61         std::cout << "Failed to initialize GLAD" << std::endl; return -1;
 62 
 63     }
 64 
 65     // render loop
 66 
 67     // -----------
 68 
 69     while (!glfwWindowShouldClose(window))
 70 
 71     {
 72 
 73         // input // -----
 74 
 75         processInput(window);
 76 
 77         // glfw: swap buffers and poll IO events (keys pressed/released, mouse moved etc.)
 78 
 79         // -------------------------------------------------------------------------------
 80 
 81         glfwSwapBuffers(window);
 82 
 83         glfwPollEvents();
 84     }
 85 
 86     // glfw: terminate, clearing all previously allocated GLFW resources. 
 87     // ------------------------------------------------------------------ 
 88     glfwTerminate(); return 0; 
 89 } 
 90 // process all input: query GLFW whether relevant keys are pressed/released this frame and react accordingly 
 91 // --------------------------------------------------------------------------------------------------------- 
 92 void processInput(GLFWwindow *window) 
 93 { 
 94     if(glfwGetKey(window, GLFW_KEY_ESCAPE) == GLFW_PRESS) 
 95         glfwSetWindowShouldClose(window, true); 
 96 }
 97  // glfw: whenever the window size changed (by OS or user resize) this callback function executes 
 98  // --------------------------------------------------------------------------------------------- 
 99 void framebuffer_size_callback(GLFWwindow* window, int width, int height) 
100 { 
101     // make sure the viewport matches the new window dimensions; note that width and 
102     // height will be significantly larger than specified on retina displays. 
103     glViewport(0, 0, width, height); 
104 }
