[Insight-users] Fwd: Coordinate system in BinaryMask3DMeshSource

[Luis Ibanez]

Hi Yoav,



1) The BinaryMask3DMeshSource produces as output a Mesh whose
    vertices are located in PhysicalSpace, not in Index space.

    You can see this from lines 2371-2373 of the file:

             Insight/Code/Algorithms/
                  itkBinaryMask3DMeshSource.txx



2)  The DeformableMesh3DFilter has inded a bug in it, since
     it assumes that the points are in index space, as you can
     see from lines 559-561 of the file:

            Insight/Code/Algorithms/
                 itkDeformableMesh3DFilter.txx


      Could you please report this as a bug in the MANTIS bug tracker?

             http://public.kitware.com/Bug/main_page.php



       In the meantime, you may want to take a look at the
       application:


         InsightApplications/DeformableModelSimplexMesh/

       that uses the DeformableSimplexMesh3DFilter.



   Regards,


       Luis
