OpenGL(2)-窗口

写在前面

通过本节，你可以毫不费力的--->创建一个窗口

OpenGL中窗口，即载体

导入头文件

#include <glad/glad.h>
#include <GLFW/glfw3.h>

初始化glfw窗口

1     glfwInit();
2     glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
3     glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
4     glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
5 #ifdef __APPLE__
6     glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
7 #endif 

创建窗口 

 1     //创建窗口
 2     GLFWwindow* window = glfwCreateWindow(800, 600, "LearnOpenGL", NULL, NULL);
 3     // 防止创建失败
 4     if (window == NULL){
 5         std::cout<< "Failed to create glfw window" << std::endl;
 6         glfwTerminate();
 7         return -1;
 8     }
 9     glfwMakeContextCurrent(window);
1011     
12     if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))
13     {
14         std::cout << "Failed to initialize GLAD" << std::endl;
15         return -1;
16     }

窗口长存 

1     // 避免闪退，监听输入事件
2     while(!glfwWindowShouldClose(window))
3     {
4         if(glfwGetKey(window, GLFW_KEY_ESCAPE == GLFW_PRESS))
5             glfwSetWindowShouldClose(window, true);
6 
7         glfwPollEvents();
8     } 

总结

这一节是入门章节，就是先搞一个窗口出来，方便我们以后的测试，下一节开始实现具体的渲染
