Given that I have polydata I would like to know if there is a filter that will give me the polygons that are in the resulting 2D polydata. Some of the polygons that I see on the screen are also not closed, i.e. there are gaps in the contour lines. Would there be a way to close the gaps and get a list of the polygons using VTK? I need this so that I can use the pointinpolygon method with my data.<br></span></div><div style="color: rgb(0, 0, 0); font-size: 13.3333px; font-family: arial,helvetica,sans-serif; background-color: transparent;
