一、環境
- Windows 10 64位家庭版
- vs版本：Visual Studio 2017
二、配置OpenGL所需
- GLFW
- GLAD
三、步驟
1.配置GLFW
- 進入官網下載GLFW並解壓：GLFW下載
- 這里選擇32位的，因為64位的可能有些問題
- 進入VS2017創建空項目，在項目文件夾下創建includes和libs兩個文件夾（如創建項目OpenGL，則為OpenGL/OpenGL/includes）
- 將解壓文件中lib-vc2017文件夾下的.lib文件拷貝進剛剛創建的libs下，同時將include下的.h文件拷貝進剛剛創建的includes下
- 在項目名處右鍵->屬性->VC++目錄->引用目錄->編輯：粘貼項目文件夾下的.h文件所在目錄
- 同理，庫目錄->編輯：粘貼項目文件夾下的.lib文件所在目錄
- 接着將為項目添加依賴項：仍然是屬性->鏈接器->輸入->附加依賴項->編輯，將opengl32.lib，glfw3.lib，msvcrt.lib添加進去
2.GLAD
- 進入GLAD官網：GLAD下載
- Language選C\C++，Profile選core，version根據需要選擇（3.3版本及以上），然后GRNERATE，之后選擇zip文件下載並解壓
- 將include下的.h文件全部拷貝進項目文件夾下的includes下，將src下的glad.c拷貝進項目文件夾下
- 然后進入vs，添加源文件->現有項，將glad.c添加進項目
- 至此庫文件配置完成，接下來測試是否能正常使用OpenGL
3.測試OpenGL
- 創建源文件，首先需要引用glad.h和glfw3.h文件
- 因為使用的是自己添加的文件，這里引用需要使用“ “而非<>，使用” “時，它會自動出現你所添加的目錄
-
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 }
- 出現圖示窗口即可正常使用OpenGL
- 若出現報錯：默認庫MSVCRTD與……沖突，屬性->鏈接器->輸入->忽略特定默認庫->編輯，將MSVCRTD.lib添加進去即可
最后推薦一個學習OpenGL的網站，教程很舒服，本博客的測試源碼也出自此：
