[Insight-users] Copy Mesh Points and Cells to QuadEdgeMesh using MeshToMeshFilter

[Luis Ibanez]

Hi Stefan,

the itkMeshToMeshFilter is an abstract class
that only serves as base class for other filters.

See the inheritance diagram in:
http://www.itk.org/Doxygen/html/classitk_1_1MeshToMeshFilter.html

You may want to try

itkQuadEdgeMeshToQuadEdgeMeshFilter.txx
http://www.itk.org/Doxygen/html/classitk_1_1QuadEdgeMeshToQuadEdgeMeshFilter.html

and to use an itkQuadEdgeMesh type for the
reader that gets the input mesh from the .meta
file.


     Regards,


        Luis
