OpenGL 使用GLFW创建全屏窗口

GLFW库里面的glfwCreateWindow()函数是用来创建窗口的函数。

这样函数的原型是：

GLFWwindow* glfwCreateWindow(int width, int height, const char * title, GLFWmonitor * monitor, GLFWwindow * share);

介绍glfwCreateWindow()函数的使用方法

程序

    bool isFullScreen = true;

    GLFWmonitor* pMonitor = isFullScreen ? glfwGetPrimaryMonitor() : NULL;

    GLFWwindow* window = glfwCreateWindow(WIDTH, HEIGHT, "Holographic projection", pMonitor, NULL);

    //GLFWwindow* window = glfwCreateWindow(WIDTH, HEIGHT, "Holographic projection", nullptr, nullptr);

    // Define the viewport dimensions

    //glViewport(0, 0, WIDTH, HEIGHT);

    glViewport(0, 0, Screen_Width, Screen_Height);

OpenGL GLFW 指定屏幕 全屏显示

程序

     bool isFullScreen = true;

     int monitorCount;

    //GLFWmonitor* pMonitor = isFullScreen ? glfwGetPrimaryMonitor() : NULL;

    GLFWmonitor** pMonitor = isFullScreen ? glfwGetMonitors(&monitorCount) : NULL;

    std::cout << "Screen number is " << monitorCount << std::endl;

    //GLFWmonitor** pM = pMonitor;

    int holographic_screen = -1;

    for(int i=0; i<monitorCount; i++){

        int screen_x, screen_y;

        const GLFWvidmode * mode = glfwGetVideoMode(pMonitor[i]);

        screen_x = mode->width;

        screen_y = mode->height;

        std::cout << "Screen size is X = " << screen_x << ", Y = " << screen_y << std::endl;

        if(screen_x==1920 && screen_y==1080){

            holographic_screen = i;

        }

    }

    std::cout << holographic_screen << std::endl;

    GLFWwindow* window = glfwCreateWindow(screenWidth, screenWidth, "Holographic projection", pMonitor[holographic_screen], NULL);

    // Define the viewport dimensions

    //glViewport(0, 0, WIDTH, HEIGHT);

    glViewport(0, 0, Screen_Width, Screen_Height);
