vtk_clear (was Re: octaviz without render window)

[Jonathan Stickel]

Lieven

The command vtk_clear should clear anything "plotted" (by vtk_surf, 
etc), the title, and scalarbar.  It leaves the outline and axes labels. 
 If you think it is not doing what you expect, please provide an example.

By the way, most of the octaviz high level functions are largely vtk 
commands written in m-files.  Feel free to look inside the m-files to 
see how things work.  Contributions of new functions or proposed 
modifications to existing functions will be welcome.  The place to make 
suggestions is through the tracker or forums section of the octaviz 
project site (http://sourceforge.net/projects/octaviz/).

Regards,
Jonathan
