[Paraview] questions re VTK-formatted file

[pat marion]

For the color map question you asked inside your link, maybe you could
double check the colormap you created.  Paraview's colormap editor can be a
bit touchy, and it's easy to accidentally add extra points.  When I tried
your example data, it correctly colored the point with scalar value 1 using
the default color map.

Try running clean-to-grid filter before you run the contour filter.  Clean
to grid will convert the image data to unstructured grid data.  The contour
filter will work after that.  Maybe someone else can tell you why it doesn't
work without conversion.

Paraview is being clever, and displaying your data by default in a "2D
View."  The output of the contour filter is displayed in the 3D view, so
that's why a new view pops open.  After you open your data, you can
right-click the area above the render view and choose "Covert To" in the
context menu to convert the 2D view to a 3D view.
