vtkQuadricDecimation filter produces bad geometry in output
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
vtkQuadricDecimation filter can introduce non-manifold faces and isolated vertices (i.e. unused vertices which have not been removed by edge collapsing process).
The problem arises when decimating particular polydata meshes. I do not have one small enough to upload, but it happens consistently.
