OpenGL 使用GLFW创建全屏窗口

OpenGL 使用GLFW创建全屏窗口

GLFW库里面的

glfwCreateWindow()

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);
