Support for OpenGL — PyQt 5.6 Reference Guide

# Support for OpenGL

When compiled against Qt v5.1 or later, PyQt5 implements a set of either desktop QOpenGL bindings or OpenGL ES v2 bindings depending on how Qt was configured. This removes the dependency on any third-party OpenGL bindings such as `PyOpenGL`.

At the moment the desktop bindings are for OpenGL v2.0 and are mostly complete. Other versions will be added in later releases. If there are calls which you need, but are currently unsupported, then please ask for the support to be added.

Obtaining an object that implements the bindings for a particular OpenGL version and profile is done in the same way as it is done from C++, i.e. by calling `versionFunctions()`. In addition, the bindings object also contains attributes corresponding to all of the OpenGL constants.
