I made it for a company wanting to visualize the solutions of numerical
differential equation solvers (1e6 nodes or more).  The company is very
happy with IVuPy.

I do not use it myself, so I don't maintain it.  However all SIP files
have been generated by a Python script, so it may be "easy" to bring
it up to date.  The C++ headers of the Coin library are transformed
to XML using gccxml, and the xml files to SIP files.  Coin is very
orthogonal, so it did not take much time (a few months of spare time).

Coin is a scene graph library sitting on top of OpenGL.  I have looked
at several scene graph libraries and concluded that Coin was fast and
easy to interface to Python.
 
The company was using older wrappers around VTK and complaining that
VTK was a memory hog.  It is true that Coin is much faster than VTK
for scenes with many nodes.  I do not know TVTK.

You may also look at Pivy.  Pivy is based on SWIG and you may not
be able to reimplement virtual C++ function.  However, Pivy has
other advantages.
