[Insight-users] Gradient Vecotr Flow Snake in itk

[xujf]

hello, Luis:

     In the examples you descriped, I only find the tranformation from itkSimplexMesh to vtkPolyData
and the transformation from itkMesh to vtkUnstructedGrid. the method that transforms itkMesh to vtkPolyData is not found.  Is there any method that transforms itkMesh to vtkPolyData?
     
     I just tried to translate my semgmentation result which is itkMesh to vtkUnStructedGrid (according the example InsightApplications/Auxiliary/vtk/vtk2itk.cxx),then I  visulize the result. however the result is very bad, and the surface of the result is not smooth.

    my ultimate aim is to realize tranditional snake or GVF snake. I wonder whether ITK provider such 
classes to realize it?

Best Regards!
xujf

Hi Xujf

You will find multiple examples on how to convert an ITK
itk::Mesh in to a VTK vtkPolyData in the directory

          InsightApplications/Auxiliary/vtk


you will also find an example on this in the demo application


   InsightApplications/DeformableModelSimplexMesh



Regards,


   Luis
