[vtkusers] Does vtkImageBlend or vtkAppendPolyData generate 3D / Volumetric representation of 2D Image Data or PolyData respectively

[Neel007]

Hi Cory,

Thanks a lot, I will try using "vtkExtractVOI" to see if it can perform the
thresholding operation in more memory efficient way.
 
Just wondering "vtkExtractVOI" will extract the least possible volume that
contains the object right based on the "setVOI" coordinated manually set by
the user right? Is there any way to get the extent of the object in the
entire 3D volume from the output of the 3D tiff reader? 

Thanks.
