extract closed loops (polygons) from lines and polylines
This filter takes an input consisting of lines and polylines and constructs polygons (i.e., closed loops) from them. It combines some of the capability of connectivity filters and the line stripper to produce manifold loops that are suitable for geometric operations. For example, the vtkCookieCutter works well with this filter.
Note that the input structure for this filter consists of points and line or polyline cells. All other topological types (verts, polygons, triangle strips) are ignored. The output of this filter is by default manifold polygons. Note however, that optionally polyline loops may also be output if requested.

Indicate whether to clean the output points.
Cleaning means discarding any points that are unused by the output polylines or polygons. This results in a potential renumbering of the points. By default, cleaning points is on. (This feature is useful because some filters output points in addition to those used to represent output lines and polylines, and this method is faster than using vtkCleanPolyData/vtkStaticCleanPolyData).
