It would be nice for FOAC to have Python interface to ParaView, rather than VTK, since most of our intended users would prefer the readymade, easier-to-learn ParaView visualization system over the raw VTK which may take a steeper learing curve. ParaView has its own classes of Python wrapping interfaces as well so I'm guessing it shouldn't be that difficult.
An introduction to ParaView Python scripting can be found at http://paraview.org/Wiki/ParaView/Python_Scripting . Another source of information is The ParaView Guide book (may be a bit old-ish though since it's written for ParaView 3.2).
