pyGameMath Build Status Code Health Codacy Badge
This is a math library written in python for 2D/3D game development
which is also compatible with pypy. I made it while I was learning
more about the math used in graphics development and for personal use
in OpenGL related projects.
It’s still a work in progress.
It uses six to allow support between python2.x and python3.x.
To install the library just do
pip install gem
It will install the dependicies automatically.
The examples on how to use the library and more info are maintained on the github wiki:
