Overview

This is a simple example of using the OpenGL Core Profile (aka "modern" OpenGL) with PyQt, numpy, and PyOpenGL.

The DemoCanvas class is a good starting point to explore the demo code. It derives from Canvas which derives from QGLWidget.

I've provided translation, look_at, and projection functions in utility.py. For a more thorough set of affine transformations wih numpy, take a look at some code from Christoph Gohlke:

Build Instructions for Mac

Install Qt for Mac

brew install qt

Hack, Build, and Install PyQt for Mac

Here's some hackery to get core profile to work on mac.

1. wget http://downloads.sf.net/project/pyqt/sip/sip-4.13.3/sip-4.13.3.tar.gz
2. build & install sip in the usual way
3. wget http://downloads.sf.net/project/pyqt/PyQt4/PyQt-4.9.4/PyQt-mac-gpl-4.9.4.tar.gz

Next you'll build PyQt using some hacks I've provided to get core profile working on Lion. Qt doesn't support core profile for Lion at the time of this writing.

tar xvf PyQt-mac-gpl-4.9.4.tar.gz
mv PyQt-mac-gpl-4.9.4 PyQt4
cp -r pyqt-hacks/ PyQt4 ; # trailing slash required to overlay files
cd PyQt4
python ./configure.py --confirm-license \
       --bindir=/usr/local/Cellar/pyqt/4.9.4/bin \
       --destdir=/usr/local/Cellar/pyqt/4.9.4/lib/python2.7/site-p
make -j2
sudo make install
cd ..; mv PyQt4 PyQt4.done

After the make, you might see an error about virtual being outside a class. Sometimes %TypeCode doesn't work as expected and sip places the chooseMacVisual method outside the class declaration, in which case you'll need to hand-edit the generated file (./QtOpenGL/sipQtOpenGLQGLContext.cpp) and copy-paste it into the class declaration.
