[vtkusers] Exporting RIB components via vtkRIBExporter?

[W.T. Bridgman]

I can't find this in the mailing list archives, so let me make sure I'm 
not trying to re-invent the wheel...

I'd like to use VTK to generate some isosurfaces and geometry for some 
datasets, but then want to export the resulting objects into a RIB file 
where the camera, lighting, texturing, and additional contextual 
objects are controlled from another program.

Is there any practical way of exporting, say, just the polygons of an 
isosurface to a RIB file?

Looking at the class docs, it looks like I could subclass 
vtkRIBExporter to access some of the protected functions in C++, but 
I'd prefer a python solution.

Ideas?  Pointers?  Sample code?

Thanks,
Tom
