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
- 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
#include"includes/glad.h" #include"includes/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); }
- 出现图示窗口即可正常使用OpenGL
- 若出现报错：默认库MSVCRTD与……冲突，属性->链接器->输入->忽略特定默认库->编辑，将MSVCRTD.lib添加进去即可
