Detailed Description

merge duplicate points, and/or remove unused points and/or remove degenerate cells

vtkCleanPolyData is a filter that takes polygonal data as input and generates polygonal data as output. vtkCleanPolyData will merge duplicate points (within specified tolerance and if enabled), eliminate points that are not used in any cell, and if enabled, transform degenerate cells into appropriate forms (for example, a triangle is converted into a line if two points of triangle are merged).

Conversion of degenerate cells is controlled by the flags ConvertLinesToPoints, ConvertPolysToLines, ConvertStripsToPolys which act cumulatively such that a degenerate strip may become a poly. The full set is Line with 1 points -> Vert (if ConvertLinesToPoints) Poly with 2 points -> Line (if ConvertPolysToLines) Poly with 1 points -> Vert (if ConvertPolysToLines && ConvertLinesToPoints) Strp with 3 points -> Poly (if ConvertStripsToPolys) Strp with 2 points -> Line (if ConvertStripsToPolys && ConvertPolysToLines) Strp with 1 points -> Vert (if ConvertStripsToPolys && ConvertPolysToLines && ConvertLinesToPoints)

Cells of type VTK_POLY_LINE will be converted to a vertex only if ConvertLinesToPoints is on and all points are merged into one. Degenerate line segments (with two identical end points) will be removed.

If tolerance is specified precisely=0.0, then vtkCleanPolyData will use the vtkMergePoints object to merge points (which is faster). Otherwise the slower vtkIncrementalPointLocator is used. Before inserting points into the point locator, this class calls a function OperateOnPoint which can be used (in subclasses) to further refine the cleaning process. See vtkQuantizePolyDataPoints.

Note that merging of points can be disabled. In this case, a point locator will not be used, and points that are not used by any cells will be eliminated, but never merged.

Warning: Merging points can alter topology, including introducing non-manifold forms. The tolerance should be chosen carefully to avoid these problems. Subclasses should handle OperateOnBounds as well as OperateOnPoint to ensure that the locator is correctly initialized (i.e. all modified points must lie inside modified bounds).; If you wish to operate on a set of coordinates that has no cells, you must add a vtkPolyVertex cell with all of the points to the PolyData (or use a vtkVertexGlyphFilter) before using the vtkCleanPolyData filter.
