I've noticed that if I first read a structured points file with
vtkStructuredPointsReader and then immediately write it with
vtkStructuredPointsWriter (or anytime thereafter), the scalar name set in
the original foo.vtk file is lost and it defaults to the name "scalars".
If I explicitly say
it still writes out 'scalars' as the name. Now, if I set the scalar name
explicitly with the writer, it writes out 'elevation'. ie
To further complicate things, if I add more arrays of scalar data with
GetPointData().AddArray(myArray) it does not append not merely append the
extra arrays when I write the structuredpoints object to file. It mix and
matched the arrays. In one instance, with the additional arrays,
elevation was written second in the file and the name showed up....so it
is there, something is just not allowing it to write the name to the file
when it shows up first in the file. To clarify all of this, it would
appear that StructuredPointsWriter uses a default name 'scalars' for the
first scalar written to file, unless explicitly set within the writer object.
With additional arrays, it does not just append them on to the
original pointdata, but alters the order (how/why?). Am I doing something
incorrectly? This all seems pretty straightforward. As reference I am
using java + vtk 4.0. Any thoughts?
