Actually something almost exactly similar has already been done.  It
is not in the VTK source tree but is based on the GL2PS library of
Christophe Geuzaine http://www.geuz.org/gl2ps/

A recent message on the vtkusers list also showed how to integrate VTK
and GL2PS:

I believe the approach is similar (using feedback mode - whatever that
means).

The only problem with this stuff is that it isnt part of VTK itself.

It would be wonderful if a PostScript export class based on GL2PS
could eventually become part of VTK. :)

Hope this helps,
