[vtkusers] Closed Surface from Marching Cubes

[Andrew Crozier]

Hi,

I am using vtkDiscreteMarchingCubes to generate a surface mesh from a 
segmented image volume, prior to applying a custom smoothing algorithm 
and finally rendering a new image volume.

The rendering step has problems when the surface mesh is not closed, 
which occurs when the segmented object meets a side of the image volume. 
Is there some way that I can generate a closed surface from the marching 
cubes algorithm, or postprocess the open surface (or contours generated 
from it by vtkCutter) to close it?

Many thanks,
Andrew
