snap.py is a simple python package that does some of what
QGLViewer does, but in pure python. It
provides a QGLWidget with basic viewing features.
The goal is to have something easy to hack from for trying stuff out.
There is a subtree branch you can easily add as a submodule into an
existing git repository using:
git submodule add -b subtree git@github.com:maxime-tournier/snap.py.git snap
