I am using vtkLineWidget2 attached to vtkRenderWindow.
Is it possible to extract the points near(or along the vtkLineWidget2) the vtkLineWidget2?
I would like to render the profile to the vtkChartXY by using the extract points.
Now, I have a problem with the algorithm that extracts the points, so it doesn’t work well.
Could you please advise me?
Thank you !
