    Question Statement Marks=15
    Question # 1:
    Write a program using Open GL Programming to create a window as shown in the below image. The title of window should be your Student Id and your Name. You can fill the window area with any color.

    Hint: Initialize the GLFW and GLEW libraries using the commands glfwInit() and glewInit() respectively.

    Question # 2:
    What are the Open GL Buffers and how can you create and allocate these buffers. Discuss with an example.

    Note: Only write the statement of creation and allocation. No need to write the complete program.

    Question # 2:
    What are the Open GL Buffers and how can you create and allocate these buffers. Discuss with an example.

    Nearly everything you may ever do with OpenGL will involve buffers full of data. Buffers in
    OpenGL are depicted as buffer objects. As with several things in OpenGL, buffer objects are
    named using GLuint values. Values are stored using the glGenBuffers () command.
    Example: void glGenBuffers(GLsizei n, GLuint *buffers);
    After calling glGenBuffers(),you will have an array of buffer object names in buffers, but at this
    time, they’re simply placeholders. They’re not really buffer objects yet. The buffer objects
    themselves don’t seem to be really created till the name is first sure to one of the buffer binding
    points on the context. this can be important as a result of OpenGL could build choices regarding
    the most effective way to assign memory for the buffer object based on where it’s bound.

    {
    glfwTerminate();
    return -1; }
    glfwMakeContextCurrent(window); glViewport(0, 0, 800, 800); glClearColor(30, 20, 40, 0); glClear(GL_COLOR_BUFFER_BIT); glfwSwapBuffers(window);
    while (!glfwWindowShouldClose(window)) {
    glClearColor(30, 40, 0, 0); glClear(GL_COLOR_BUFFER_BIT); glfwSwapBuffers(window); glfwPollEvents();
    }
    glfwTerminate(); }
