10 // Window dimensions
11 const GLuint WIDTH 800, HEIGHT 600;
12
13 void key_callback(GLFWwindow* window, int key, int scancode, int action, int mode)
14 {
15 std::cout key std::endl;
16 // When a user presses the escape key, we set the WindowSouldlose propert to ture
17 // closing the application
18 if (key GLFW_KEY_ESCAPE action GLFW_PRESS)
19 glfwSetWindowShouldClose(window, GLFW_TRUE);
20 }
21
22 // The MAIN function, from here we start the application and run the game loop
23 int main()
24 {
25 // Init GLFW
26 glfwInit();
27 // Set all the required options for GLFW
28 glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
29 glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
30 glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
31 glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);
32
33 // Create a GLFWwindow object that we can use for GLFWs functions
34 GLFWwindow* window glfwCreateWindow(WIDTH, HEIGHT, OpenGL, nullptr, nullptr);
35 if (window nullptr)
36 {
37 std::cout Failed to create GLFW window std::endl;
38 glfwTerminate();
39 return -1;
40 }
41 glfwMakeContextCurrent(window);
42 // Set the required callback function
43 glfwSetKeyCallback(window, key_callback);
44 // Set this to true so GLEW knows to use a modern approach to retrieving
45 // function pointers and extensions
46 glewExperimental GL_TRUE;
47 // Initialize GLEW to setup the OpenGL Function pointers
48 if (glewInit() ! GLEW_OK)
49 {
50 std::cout Failed to initialize GLEW std::endl;
51 return -1;
52 }
53
54 // Define the viewport dimensions
55 int width, height;
56 glfwGetFramebufferSize(window, width, height);
57 glViewport(0, 0, width, height);
58
59 // Game loop
60 while (!glfwWindowShouldClose(window))
61 {
62 // Check if any events have been activiated (key pressed, mouse moved etc.)
63 // and call corresponding response functions
64 glfwPollEvents();
65
66 glClearColor(0.2, 0.3, 0.4, 1.0f);
67 glClear(GL_COLOR_BUFFER_BIT);
68
69 // Swap the screen buffers
70 glfwSwapBuffers(window);
71 }
72
73 // Terminate GLFW, clearing any resources allocated by GLFW.
74 glfwTerminate();
75 return 0;
