[Insight-users] Re: some problems in Examples/Segmentation/DeformableModel1.cxx

[Luis Ibanez]

Hi Funchun,

In order to display a Mesh you can use VTK.

in the InsightApplications checkout, you will
find examples on how to convert an ITK mesh
into a VTK one. Please look at the file

InsightApplications/Auxiliary/vtk/vtk2itk.cxx


In order to display the gradient vector field
you can also use VTK, in particular you may
want to use Glyphs.  You may want to play with
ParaView in order to get a feeling on how the
vector field can be displayed.

ParaView is an open source, free application
developed on top of VTK. It reads MetaImage
files and can be downloaded from

      http://www.paraview.org


The Deformable models can be used in 3D.
The examples for the SoftwareGuide were mostly
done in 2D simply because it was easier to
display the results in that way.


Please let us know if you have further questions.



  Thanks


     Luis
