A cross platform helper library for ModernGL making window creation and resource loading simple. It can also be used with PyOpenGL for rendering with the programmable pipeline.

Please report bugs or post questions/feedback on github.
- Cross platform support. Tested on Windows 10, Linux and Mac OS X. This can save users a lot of time and is often more difficult than most people imagine it to be.
- Easily create a window for ModernGL using pyglet, pygame, PySide2, GLFW, SDL2, PyQt5 or tkinter supporting a wide range of window, keyboard and mouse events. These events are unified into a single system so your project can work with any window.
- Load 2D textures and texture arrays
- Load shaders as single or multiple
- Load objects/scenes from wavefront/obj, GLTF 2.0 or STL
- Resource finder system supporting multiple resource directories
- A highly plugable library supporting custom loaders, resource finders and windows.
- Type hints everywhere making code completion and linting a breeze
We are not trying to force the user into using every aspect of this
library. If you have an exiting project and just need texture loading
you will be able to do this without unnecessary hurdles as long as
you provide us your
pip install moderngl-window
- Mac OS X
Simple example opening a window clearing every frame using red (color).
# test.py import moderngl_window as mglw class Test(mglw.WindowConfig): gl_version = (3, 3) def render(self, time, frametime): self.ctx.clear(1.0, 0.0, 0.0, 0.0) mglw.run_window_config(Test)
Run the example with different window backends:
python test.py --window pyglet python test.py --window pygame python test.py --window glfw python test.py --window sdl2 python test.py --window pyside2 python test.py --window pyqt5 python test.py --window tk
WindowConfig classes are the simplest way to get started without knowing
a lot about this library. For more advanced usage see documentation
Setup from source
We assume the user knows how to handle vitrualenvs.
# Install the package in editable mode $ pip install -e . # Set up and dev requirements pip install -r requirements.txt pip install -r tests/requirements.txt
Tests are set up with
tox running pytest with coverage and flake8.
pip install -r tests/requirements.txt tox -e py35 tox -e py36 tox -e py37 tox -e py38 tox -e pep8
pip install -r docs/requirements.txt python setup.py build_sphinx
Contributions are welcome regardless of experience level. Don't hesitate submitting issues, opening partial or completed pull requests.
We are interested in contributions providing new loaders, windows etc. For these to be included in this library we require them to work cross platforms (win10/linux/osx) and be fairly easy to set up.
If it requires more than manually downloading a pre-compiled dll (like SDL2, GLFW etc.) it would most likely not be included, but you are welcome to present your case if you still think it should be included.
If you create your own repo/package containing plugins for
this library, please make an issue and we'll link back to it.
Be sure to include what platforms are supported, install
instructions, how you configure it in
of course a clear and concise description of what exactly
your package provides.
We can't build everything from scratch. We rely on certain packages and resources to make this project possible.

The majority of the code in this library comes from demosys-py (somewhat modified).
demosys-py is a framework we decided to split out a lot useful functionality into this
library. Frameworks are a lot less appealing to users and it would be a shame to not make this
more available to the ModernGL user base.
