So I have a PolyData object of lines generated from extracting feature edges from a 2D unstructured grid and then cutting out portions of the feature edges I didn’t want.
In my example, the original grid was just a square, so the feature edges would equally just be a square. Then I “extracted” out one side of the square. I would like to have the points of this PolyData object be in the order of the line, as currently they are more-or-less random.
From this definition on the VTK examples website, maybe the solution would be to convert the PolyData to a PolyLine? I can’t find any obvious path to achieve this though.
