[Paraview] Volume-rendering actual volume data, already written in VTK?

[Adam M. Smith]

Hi All,

I'm looking at the VTK documentation and there seems to be a rich
collection of subclasses of vtkVolumeMapper including many that require no
special hardware.  How come Paraview only with the
vtkUnstructuredGridVolumeMapper side of the family?  I would think that
including all of these other methods would only be as hard as writing some
cxx/xml to wrap them in the server manager and adding some UI switches to
select between them on the client side.   Is there significantly more to
it than this that has kept others from doing it already?
