[vtkusers] Fixing vtkPolyDataToImageStencil

[Ryan A Whitley]

David,

I have noticed that if I run my data through vtkCleanPolyData with a tolerance of 1e-3, then this will removes the artifact.  I should also note that this artifact is also seemingly random throughout my dataset.

David,
My tolerance was set to 0 in this example.

I’m attaching the data set that generated the image.  It was generated by using vtkCutter to slice a surface with a plane, followed by vtkStripper.  My volume spacing was set to 1.5 in all directions.


Regards,
- Ryan

Thanks for the feedback, Ryan.  What is your tolerance set to?  If it wasn't
set to zero, can you try it again with a tolerance of zero?

Also, a description of the data set (or even better, the data itself) would be
very useful.
