[vtkusers] vtkPolyLine create a line

[Jonathan Ruiz Peinado]

Hi I'm trying to do a simple line using vtkPolyLine, to pass it
to vtkSplineFilter.

This example
http://www.vtk.org/Wiki/VTK/Examples/Cxx/GeometricObjects/PolyLine
shows how to do it but is using some methods that I can't find in my vtk
libs "vtkPolyLine.GetPointIds()"


This code use to works but I don't know how it does

polyLine.SetPoints(pathPoints);
polyLine.SetLines(cellArray);

vtkPoints pathPoints, has 2 or more points
but not sure what I've to do with the cellArray, ¿ what I've to put in
there?.

¿ Do somebody got some example about how to do it or can tell me how it
works ?

Thanks!
