[vtkusers] Surface Extraction : vtkMarchingCubes

[Taru S]

Hello VTK-Developers,

I need your advise regarding the correct usage scenario for
vtkDiscreteMarchingCubes. I have a segmented labeled volume (for some of the
anatomical structures) with integer values for each of the segmented
labels.

I am able to extract the iso-surfaces using the MarchingCubes(discrete) so
far. If I am not mistaken, this filter or the Contour filter  may not work
for structures/labels with very close boundaries (i.e. there may be more
than one structure with iso value < iso value for a particular str). Is
there any way to work around this issue in vtk?

Other possibility is to use some kind of binary threshold to mask the
unwanted regions. Would it be right to use ITK (confidence connected,
binaryThreshold ??) followed by AntiAlias filter? or is there anything
available in VTK for the same?

I will appreciate your response.

Taru
