[vtkusers] VTK External file

[Lubos Brieda]

another option would be to write your own file reader. I have done this in the past to accomplish basically the same thing you want and it worked out great. You don't  have to use VTK's file readers to create data sources, you can build them internally in your program using data parsed from your own input file.

I recommend using the xdmf file format instead for static geometry
with variable attributes. See an example at:
http://paraview.org/Wiki/Data_formats

xdmf is not yet distributed with vtk (it is with paraview) but you can
compile xdmf standalone and use it with vtk.
