编写主函数F5运行

#include <GLFW/glfw3.h>

int main(void)

{

    GLFWwindow* window;

    /* Initialize the library */

    if (!glfwInit())

        return -1;

    /* Create a windowed mode window and its OpenGL context */

    window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);

    if (!window)

    {

        glfwTerminate();

        return -1;

    }

    /* Make the window's context current */

    glfwMakeContextCurrent(window);

    /* Loop until the user closes the window */

    while (!glfwWindowShouldClose(window))

    {

        /* Render here */

        glClear(GL_COLOR_BUFFER_BIT);

        /* Swap front and back buffers */

        glfwSwapBuffers(window);

        /* Poll for and process events */

        glfwPollEvents();

    }

    glfwTerminate();

    return 0;

}

画个三角形:

#include <GLFW/glfw3.h>

int main(void)

{

    GLFWwindow* window;

    /* Initialize the library */

    if (!glfwInit())

        return -1;

    /* Create a windowed mode window and its OpenGL context */

    window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);

    if (!window)

    {

        glfwTerminate();

        return -1;

    }

    /* Make the window's context current */

    glfwMakeContextCurrent(window);

    /* Loop until the user closes the window */

    while (!glfwWindowShouldClose(window))

    {

        /* Render here */

        glClear(GL_COLOR_BUFFER_BIT);

        // Draw triangles begin

        glBegin(GL_TRIANGLES);

        glVertex2f(-0.5f, -0.5f);

        glVertex2f(0.0f, 0.5f);

        glVertex2f(0.5f, -0.5f);

        glEnd();

        // Draw triangles end

        /* Swap front and back buffers */

        glfwSwapBuffers(window);

        /* Poll for and process events */

        glfwPollEvents();

    }

    glfwTerminate();

    return 0;

}
