[Paraview] External Surface and Cell Blanking (post #2)

[Kent Eschenberg]

Does anyone think this might be a bug in vtkDataSetSurfaceFilter? If so I could 
try to fix it. Its becoming a large problem for us.

I have a reader producing vtkStructuredGrid data with cell blanking that
operates as expected with a cut. However, the external surface module always
shows everything w/out respect for the blanking. This is a large, transient
data set so I'd rather not use Threshold which converts it all to an
unstructured grid.

Should the external surface module honor blanking? Is there a nice summary of
which ParaView/VTK filters honor node and/or cell blanking?

Most of the blanked cells are in groups around the edges. I could figure out
which nodes are never used and also set node blanking. Would that help?

TIA
