[Insight-users] About TransformPoint

[Alexandre GOUAILLARD]

Hi steven,

As for the TransformMeshFilter, you have a lot of errors related to your
using a pointset instead of a Mesh.
Typically, you should not be able to write this:
typedef itk::TransformMeshFilter<PointSetType, PointSetType, TransformType>
TransformFilterType;

You should write this instead
typedef itk::TransformMeshFilter<MeshType, MeshType, TransformType>
TransformFilterType;

You can mdify your code by creating a mesh, and using its SetPoints() method
to attach your instance of a Poinset.

You might want to instanciate the meshtraits manually to avoid the pointype
problem.

Alex.
