[Insight-users] How to extract a sub-mesh using itk::InteriorExteriorMeshFilter

[Vincent Gratsac]

Hi all,

Actually, it seems that cells are not modified at all. So many of them 
are using points which do not exist anymore after using the 
InteriorExteriorMeshFilter.

Is there a way to generate new cells, or to extract only cells which 
uses the extracted points ?

Any help is welcome...

Thank you,

Vincent
