[Octaviz-help] octaviz being abandoned [Fwd: Re: Octaviz patch for VTK 5.2 (incomplete)]

[Jonathan S. <jjs...@vc...>]

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 (see below).  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.

Regards,
Jonathan

Hi Jonathan,

thanks for the answer. It's a rewrite of the bison interface plus some
changes in the lexer and the wrapper. It compiles with VTK 5.2. I am
sorry, but I can't put more time into this. It should not be a lot of
work for you to diff it yourself which is why I won't send you a
patchfile.

Cheers
Andreas
