[vtkusers] Draw line with vtk

[Sankhesh Jhaveri]

Hi,

You should use the widget if you think you would like to *interactively*
place/draw and edit the line. If your goal is to just display a line given
a set of parameters and update it without interaction, a simple cell based
approach should work. See
https://lorensen.github.io/VTKExamples/site/Cxx/GeometricObjects/LongLine/

Hope that helps.
