tweaked version of planar for use in app
Planar is a 2D geometry library for Python. It is intended for use by games and interactive real-time applications, but is designed to be useful for most any program that needs a convenient, high-performance geometry API.
Planar is being developed as part of the larger Grease game framework. However, it is a standalone library and has no external dependencies besides Python, and optionally a C compiler.
Planar is purely a math library, presentation, graphical or otherwise is left up to the application.
- Do one thing, 2D geometry, and do it well.
- Provide a high-level, clean, Pythonic API.
- All APIs have both a Python reference implementation and a high performance implementation in C with the same interface.
- Compatibility with Python 2.6+, and Python 3.1+
- 100% test coverage.
- Full narrative and API reference documentation.
- Release early and often.
- Be responsive to community input.
- Don’t take ourselves too seriously.

The API for planar, and some of the code is derived from the excellent work done by the Super Effective Team, thanks guys!
Planar requires Python 2.6, 2.7, 3.1, or better.
To experience the exhilaration of native-code performance, a C compiler is required. If someone volunteers, binary releases for platforms where this is not common (you know who you are) will be happily made available.
Planar releases can be downloaded from the python package index (pypi):
You can get the latest code in development from the planar mercurial repository on bitbucket:
To build and install Planar from the source distribution or repository use:
python setup.py install
To install only the pure-Python modules without compiling, use:
python setup.py build_py install --skip-build
Only performance is sacrificed without the C extensions, all functionality is still available when using only the pure-Python modules.
Planar requires nose for testing. You can install it for Python 2.x using easy_install:
For Python 3.x, you can download and install distribute from here:
For now, you can get a copy of nose3 for Python 3.x, patched to install properly on Python 3.1 here:
Once nose is installed you can run the tests from the source directory using nosetests, first building the C extensions, like so (on Unix):
python setup.py build && nosetests -d -w build/lib.*/planar/
This runs the tests inside the build directory so that the C extensions can be tested. You can put a 3 suffix on the python and nosetests commands above for Python 3.x.
You can browse the documentation online here:
The same documentation is also available for offline browsing in the doc/build/html subdirectory of the source distribution.
