Michael,
Yes, it is. If you want to keep the hex/quad structure, you can resort
to the Threshold filter, thresholding based on coordinate values. See
yesterday's posting http://markmail.org/message/wooi4pdb7j4h6z36 on how
to get coordinates as additional data arrays. Note, though, that with
the Threshold filter you won't be able to cut through a hex, just along
its faces. So, only if the underlying hexahedra are aligned along your
chosen slice, you get be a smooth surface.
There might be another vtk filter that is unexposed in the ParaView GUI
that actually cuts through hexahedra without resorting to triangulation
of the surface. But that I don't know.
