[vtkusers] Coincident point identification

[Steve Boyd]

Hi,

Can somebody suggest a fast way to find 3D points that are coincident
(or within some tolerance of being coincident)?

I need to "fix" an vtkUnstructuredGrid mesh where neighbouring cells
have points that should be shared, but are currently duplicated.  I want
to remove the duplicate points and re-set the connectivity of the cells
appropriately.

I've been trying to use vtkExtractUnstructuredGrid with ->MergingOn(),
but have been having problems with incorrect cell connectivity on the
output.

Regards,

Steve
