[vtkusers] MPI Offscreen Volume Rendering

[Wylie, Brian]

All,

(sorry if you get a resend I had to super compress the pdf because
vtkuser was bouncing the message...)

Folks may already be aware of this, but just wanted to point out that
there is functionality in ParaView which will take an unstructured grid,
chop it up along axis aligned boundaries with D3
(vtkDataDistributionFilter) and create a DAG (Directed Acyclic Graph)
based on the current viewpoint and then alpha blend the results. Which
gives you parallel unstructured volume rendering. :)

If you want to do the same sort of thing in VTK it might be helpful to
reuse some of the functionality from ParaView or at least poke around
the code a bit.
