Python Modern Opengl GLFW Window

In this Python Modern Opengl i want to show you GLFW Window creation. So when you are going to work with Modern Opengl, for Window creation you need to use another library that is called GLFW.

Because Opengl is a graphic library and we don’t have window, keyboard inputs, mouse inputs and some other low level functionality.

So you need some installation for this article

pip install pyopengl

1	pip install pyopengl

pip install glfw

1	pip install glfw

What is GLFW ?

GLFW is an Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan development on the desktop. It provides a simple API for creating windows, contexts and surfaces, receiving input and events.GLFW is written in C and supports Windows, macOS, the X Window System and the Wayland protocol.

So now this is the complete code

import glfw





def main():

  
    if not glfw.init():
        return


    window = glfw.create_window(720, 600, "Opengl GLFW Window", None, None)

    if not window:
        glfw.terminate()
        return


    glfw.make_context_current(window)


    while not glfw.window_should_close(window):
        glfw.poll_events()
        glfw.swap_buffers(window)


    glfw.terminate()







if __name__ == "__main__":
    main()

import glfw

def main():

if not glfw.init():

return

window = glfw.create_window(720, 600, "Opengl GLFW Window", None, None)

if not window:

glfw.terminate()

return

glfw.make_context_current(window)

while not glfw.window_should_close(window):

glfw.poll_events()

glfw.swap_buffers(window)

glfw.terminate()

if __name__ == "__main__":

main()

In this line of code we have initialized the library

  if not glfw.init():
        return

1 2	if not glfw.init(): return

Now create a windowed mode window and its OpenGL context

window = glfw.create_window(720, 600, "Opengl GLFW Window", None, None)

    if not window:
        glfw.terminate()
        return

window = glfw.create_window(720, 600, "Opengl GLFW Window", None, None)

if not window:

glfw.terminate()

return

Make the window’s context current

glfw.make_context_current(window)

1	glfw.make_context_current(window)

Loop until the user closes the window

    while not glfw.window_should_close(window):
        glfw.poll_events()
        glfw.swap_buffers(window)


    glfw.terminate()

while not glfw.window_should_close(window):

glfw.poll_events()

glfw.swap_buffers(window)

glfw.terminate()

In the loop code this is for swap front and back buffers

glfw.swap_buffers(window)

1	glfw.swap_buffers(window)

This is for poll for and process the events

glfw.poll_events()

1	glfw.poll_events()

Run the code and this will be the result
