[Paraview] Modifying the filters available in Paraview ?

[Axel Steuwer]

Hi,

the code below is taken from the Mayavi code (/Misc/RenderWindow.py)
from Prabhu (thanks!)
and defines the function for exporting with the vtkGL2PSExporter.
Does that help?

        the graphics separately.

I can't :-) I never did it. Currently, there is no way of adding
exporters to ParaView using xml files. One would have to change ParaView
code to do it. If someone explains how gl2ps works 
(what calls are made to enable it etc.), I might have some pointers.
