[Paraview] Grid is shifted in different dimensions

[Andy Bauer]

Here's an example of a vtk file for a vtkImageData.  You should replace
your point_data with the stuff in cell_data and below.

# vtk DataFile Version 3.0
vtk output

DATASET STRUCTURED_POINTS
DIMENSIONS 6 6 6
SPACING 0.5 0.5 0.4
ORIGIN -1.75 -1.25 0
