Modern OpenGL 3.3+ Framework inspired by Django
A Python 3 cross platform OpenGL 3.3+ core framework based on ModernGL
Originally made for for non-interactive real time graphics combined with music ("real time music videos", see demoscene) but can of course be used almost any purpose.
Made for people who enjoy playing around with modern OpenGL without spending lots of time creating all the tooling to get things up and running. Using ModernGL also makes working with OpenGL a breeze accomplishing a lot with very few lines of code.
A high priority for this project is also to help improving ModernGL.
- ModernGL Documentation
- Effect Templates
- demosys-py on Github
- demosys-py on PyPi
- Discord Server
Creating a project with a spinning cube can be done in less than a minute.
pip install demosys-py demosys-admin createproject myproject demosys-admin createeffect myproject/cube
Now run the effect
python manage.py runeffect myproject.cube
- A simple effect system based on python packages
- Supports most modern OpenGL features through ModernGL
- Resource loading system for shader programs, textures, scenes and misc data
- Loading GLTF 2.0 and wavefront obj files/scenes
- Supports the rocket sync-tracker system to create interesting keyframe data (Using pyrocket)
- Runtime re-loading shader programs (press R)
- Supports headless rendering and various visible windows such as pyGLFW, PyQt5, PySDL2 and Pyglet.
- Management commands for creting new projects and effects including the ability to make custom commands
- A highly pluggable framework with customizable timers, resource loaders, timelines and more
- A geometry module for quick creation of common mesh/VAO types
- Experimental audio playback support
In order to use the framework it's an advantage to know the following:
- Basic or intermediate Python
- Basic glsl
- Basic matrix math
If you are missing any of these requirements the framework can definitely be used to learn. 0 lines of code are needed to generate a project with a spinning cube and you can star poking at things.
Installing the project in development mode (in a virtualenv):
python setup.py develop # PyQt5 doesn't support develop and have to manually be force-reinstalled installed after pip install -I PyQt5
# All tests pip install -r requirements-test.txt python manage.py test # Single tests module python manage.py test tests/test_effect.py
pip install -r docs/requirements.txt python setup.py build_sphinx
- ModernGL PyOpenGL replacement
- PIL/Pillow for texture loading
- Pyrrr for math (uses numpy)
- PyQt5 is default for window/context creation (works out of the box on most platforms)
- pyGLFW for window/context creation
- pyglet for window/context creation (Does not work on OS X)
- pygame using the mixer module for music
- python-vlc for audio playback
