[vtkusers] Add text to vtkPoint

[Chris Marsh]

Hi,

Shortly after my email I found that example! It got me in the right
direction, thanks.

I've figured it out and the answer is not obvious:

Use this example for writting points to a file
http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/WriteVTP

Use the example you linked for building the vtkStringArray to hold the
labels and adding it to the polydata in the above example
via
http://www.vtk.org/Wiki/VTK/Tutorials/DataStorage

Then in Paraview, choose your point data, go to spreadsheet mode, select
the points you want, then View->Selection Display Inspector. Choose the
dataarray under point labels and it will show the text next to the point.

Thanks again!
