PyGLy is a flexible OpenGL framework that works with any PyOpenGL supported Windowing system.
PyGLy provides a set of common rendering classes, but doesn't force you to use any of them.
- OpenGL agnostic - Use Legacy (<=2.1) or Core (>=3) profiles.
- Cross-platform - Actively developed on Windows, Linux and Mac OS-X.
- Easy to install - Written in pure python.
- Modular design - Take almost any part of PyGLy and use it on its own.
- Loosely coupled framework, not an engine - Don't like an existing class? Don't use it! PyGLy doesn't force any programming method on you.
- Duck-typing - Replace any class with your own.
- Full control over rendering process.
- Uses Pyrr for Maths - NumPy powered Quaternion, Matrix, Vectors, Rays.
- Liberal BSD licensing - Do what you want!
- Active development - Being developed for games.
- Platform - Windowing system agnostic.
- Viewports - Multiple viewports using simple to use wrappers.
- Optional scene objects - Scene nodes, cameras, render nodes.
- 3D transform objects - Wraps 3D maths in intuitive objects.
- GLSL shaders - Uniform and Attribute wrappers. Errors print offending source code.
- Vertex Arrays and Buffers - Basic and numpy enhanced versions. No more pointer maths.
- Sorting - Sort scene to minimise over-draw and to support transparency.
- Texture - Easily create OpenGL textures using raw data or PIL.
- View Matrices - Simple wrappers that provide easy manipulation of the view matrix.
- GL functions - Python wrappers for common tasks.
- Cocos2D - Support for rendering PyGLy as a Cocos2D layer (OpenGL Legacy only).
- FRAMEWORK, not an engine. Program any way you want.
- FLEXIBLE, don't force any one method upon the user
- FULL CONTROL at all times. Full access to rendering, objects, data. No obfuscation. No 'awesome' tricks. Just good, simple code.
- EASY INSTALLATION. No crazy C++ bindings and complex build procedures.
- EXPOSE as much functionality as possible. Lower classes are always accessible or usable on their own.
- LOOSE COUPLING. Code designed with minimal coupling, allowing you to use only what you want.
- OPTIONAL high level classes. Low level code is always usable. High level API is optional.
- EXAMPLES of high quality.
- PYTHON to the core.
- SPEED in development. Simple and Intuitive code provides convenience functions where it makes sense.
- DEFINED GOALS. PyGLy aims to provide a high quality, base. PyGLy will never become bloat-ware.
- PARTNER PROJECTS. PyGLy provides the core of our 3D stack.
PyGLy contains no platform / window specific code.
PyGLy has been tested with the following windowing systems:
Note: When using Pyglet on Mac OS-X and the OpenGL core profile, you must use the Pyglet version supplied in the /contrib/pyglet directory.
- Python 2(.6?)+
- Pyrr (https://github.com/adamlwgriffiths/Pyrr)
- PIL / Pillow (PIL texture loading)
PyGLy is available from the PyPI package repository under the name 'pygly'.
Source installation is the recommended method to use PyGLy.
Install required dependencies listed above.
And a window system of your choice.
git clone git://github.com/adamlwgriffiths/PyGLy.git cd PyGLy git submodule init git submodule update
Select one of the following:
- A. Install PyGLy and it's submodules.
- B. set the PYTHONPATH to enable each module.
cd contrib/pyrr python setup.py install cd ../../ python setup.py install
export PYTHONPATH=$PYTHONPATH:/path/to/PyGLy export PYTHONPATH=$PYTHONPATH:/path/to/PyGLy/contrib/pyrr
python pygly/examples/run_demo.py -p glut -g legacy -d basic
Check the 'pygly/examples' directory for for some example code.
