I am abandoning Octaviz.  I do not see a future with Octaviz with Octave developers fully committed to so-called 'native' graphics using fltk and opengl.  Personally, I have switched to using python/scipy with matplotlib and mayavi2, a better numerical programming language and much better plotting and visualization, in my opinion.

The last activity with Octaviz that I am aware of came from Andreas Potschka.  He attempted to fix Octaviz to compile with vtk-5.2, with limited success.  I have tried to check in his work to CVS, in case anyone wants to revive the project in the future.
