[Paraview] Volume rendering rectilinear data

Fri Apr 27 12:06:21 EDT 2018

You are correct it will not directly volume render vtkRectilinearGrids.

Use threshold filter (all values) to map to a vtkUnstructuredGrid for
direct rendering but at a cost of memory explosion.
Apply the resample to image filter to map to vtkImageData for fast volume
rendering, but at a cost of trading off precision for memory size.
