But this does not work in the case of cutting data with holes present.
vtkCutter gives me a bunch of polylines, but some are complete / closed
(for the holes generally) but larger ones are broken up into serveral
separate polylines.
Thus, throwing all the output into a stripper does not produce the desired
results.
I am aware that GlutTesselatorTriangluate or something will do this, but I
do not have access to install additional libraries on this system.
Is there maybe some flag that I can set on vtkCutter to have it -not- split
up edges into different polylines? Or a way to have vtkStripper reassemble
only the ones that go together instead of just connecting cell1 to cell2,
to cell3, to cell4?
Thanks
