[Insight-users] DeformableMesh3DFilter example doesn't change input

[Benjamin Klimczak]

Hi Luis,

thanks for looking into my problem.

I have also tried to use the 
itkDeformableSimplexMesh3DGradientConstraintForceFilter.h but I ran into 
strange template compiler errors when I created a simplex mesh, i.e. 
when I used the TriangleMeshToSimplexMeshFilter. The code of this test 
is attached.

Thanks again and best regards,
Benjamin
