Summary

0007159: vtkCleanPolyData does not remove all degenerate cells

Description

I consider a triangle of zero area to be a degenerate cell.

However, if you create a simple mesh such as

===
# vtk DataFile Version 3.0
vtk output
ASCII
DATASET POLYDATA
POINTS 5 float
0 0 0
0 100 0
0 -100 0
100 0 0
100 0 0
POLYGONS 2 8
3 0 1 2
3 2 1 3
===

...and then pass this through the vtkCleanPolyData filter, it doesn't remove the degenerate cell (0, 1, 2).

===
# vtk DataFile Version 3.0
vtk output
ASCII
DATASET POLYDATA
POINTS 4 float
0 0 0 0 100 0 0 -100 0
100 0 0
POLYGONS 2 8
3 0 1 2
3 2 1 3

CELL_DATA 2
POINT_DATA 4
===

In my view, this either requires modifying the class so that such cells are removed, or the documentation needs clarifying as to what degeneracies are removed.
