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

[Vincent Gratsac]

Hi all,

I am trying to extract a sub-mesh from another mesh by using the 
InteriorExteriorMeshFilter.

The points of the sub-mesh are well extracted, but the problem appears 
when dealing with the mesh cells.
In the filter documentation, we can read : "...attention should be paid 
to the cells because some of their points could not exist in the output 
mesh, if they did not satisfy the criterion imposed by the spatial 
function.".

Here is my problem, I don't know how to clean cells which link to points 
that do not exist in the output mesh.

Does anyone can help me ?

Thank you,

Vincent
