[Paraview] Volume rendering of CSV data

[John Haiducek]

You might have luck converting it to a structured grid. There are a
couple of filters that do that. You might need to downsample your grid
using Extract Subset first in order to get renders in a reasonable
time.

Another way would be to convert to vtkStructuredPoints first, although
I don't know a way to do that inside of paraview; I wrote a program in
C++ to do it but the input wasn't a CSV file.
