Hi there,
I am making my first attempt at 3D rendering. My system configuration:
OS : Ubuntu 16.04 64-bit
Python : 3.5.1
Qt : 5.5.1
PyQt : 5.5.1
OpenGL : 4.5.0 (I have a modern GPU)
All software was installed from the Canonical repository. I didn't build any
binaries myself.

Two weeks of searching web pages hasn't turned up a single example which
demonstrates PyQt5 doing something simple in 3D with OpenGL that I can study.
My own attempt to write such a program displays my QOpenGLWidget subclass
instance, and calls the methods I defined, but throws this exception:
ImportError: No module named 'PyQt5._QOpenGLFunctions_4_5_Compatibility'
Here's a snippet of the offending method of my QOpenGLWidget:
def initializeGL(self):
ctx = self.context() # This works, ctx is a PyQt5.QtGui.QOpenGLContext
print(ctx.versionFunctions()) # ImportError occurs here
Searching for that ImportError, I found a page which says that error occurs
when "you have a more capable version of OpenGL than PyQt has support for", but
no advice is offered on how to fix that problem.
I like the idea of using PyQt5, because I'm getting pretty familiar with it,
BUT I am open to trying any quick and clear route to 3D rendering. I would
appreciate the community's recommendations. Thanks.
