[Insight-users] deformable model in ITK

[Luis Ibanez]

Hi Kegang,


Yes,
ITK has 3D implementations of deformable models.

You may want to take a look at the application:


   InsightApplications/DeformableModelSimplexMesh


It combines the

   itkSimplexMesh.h
   itkTriangleMeshToSimplexMeshFilter.h
   itkRegularSphereMeshSource.h
   itkDeformableSimplexMesh3DGradientConstraintForceFilter.h
   itkDeformableSimplexMesh3DFilter.h


You will find paper citations in the Doxygen documentations
of these classes.

This application also illustrates how to combine ITK and
VTK for performing surface related operations.



     Regards,


        Luis
