[Insight-users] Difference between itkDeformableSimplexMesh3DFilter and itkDeformableMesh3DFilter

[Luis Ibanez]

Hi Dženan


Summary:
========

Both classes implement a Deformable Model algorithm.
The main difference between the two is that one of them
expects a Triangulated Mesh as input, while the other
one expects a Simplex Mesh as input.



Details:
======

The class:
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1DeformableSimplexMesh3DFilter.html

is an abstract class, with an specialized implementation in
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1DeformableSimplexMesh3DBalloonForceFilter.html
and
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1DeformableSimplexMesh3DGradientConstraintForceFilter.html


This filter expect as input a Simplex mesh,
which can typically be generated by the filter:
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1TriangleMeshToSimplexMeshFilter.html

For a description of the Simplex Mesh concept,
please look at
http://www-sop.inria.fr/members/Herve.Delingette/simplex/index.php



On the other hand, the class
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1DeformableMesh3DFilter.html

operates on a standard itk::Mesh.


Please note that the classes
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1DeformableSimplexMesh3DBalloonForceFilter.html
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1DeformableSimplexMesh3DGradientConstraintForceFilter.html

have been gone through a better testing and verification than
the class
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1DeformableMesh3DFilter.html



     Regards,


            Luis
