[Insight-users] Setting fixed image

Thu Feb 22 16:16:22 EST 2007

Thank you for your fast reply. I tried your suggestions .Unfortunately I could't accomplish it :( First Suggestions seems really good. But error is strange. What might the reason do you think? Sorry for my inconvenience again:(   
When I try  like that :

typedef PointSetType::PointsContainer PointsContainer;
PointsContainer::Pointer pointsContainer = PointsContainer::New();
pointsContainer = mesh->GetPoints();
 itk::PointSet<float, 3>::Pointer pointSet = itk::PointSet<float,3>::New();
pointSet->SetPoints(pointsContainer);

registrationMethod->SetFixedPointSet(pointSet);
It gives that error:
:\documents and settings\aydemir\desktop\itktovtk\teste.cpp(234) : error C2679: binary '=' : no operator found which takes a right-hand operand of type 'itk::VectorContainer<TElementIdentifier,TElement> *' (or there is no acceptable conversion)

You need to pass the point set from the mesh to the function. This is how I did it a while ago:

PointsContainer::Pointer pointsContainer = PointsContainer::New();
pointsContainer = mesh->GetPoints();

itk::PointSet<float, 3>::Pointer pointSet = itk::PointSet<float,3>::New();
pointSet->SetPoints(pointsContainer);

registrationMethod->SetFixedPointSet(pointSet);

****Note that registrationMethod is templated over itk::PointSet

I don't recall the specifics of the classes involved but you may be able to directly set the points from the mesh, i.e., registrationMethod->SetFixedPointSet(mesh->GetPoints()) if you template the registration class over itk::PointsContainer (if possible). 

registrationMethod->SetFixedPointSet(

Hi christoph;
 first of all I want to thank your kind reply. I read my stl data with VTK then I converted poly data to itk mesh. And mesh is the  result of vtkpolydata to itk mesh converting process. When I use second one (registrationMethod->SetFixedPointSet(mesh);) It gives the following error. I am really looking forward to your next reply.
Thanks 
Tony

Hi Tony,

the error message as result of the first try seems to be clear:
GetOutput() is a function e.g. of a filter, not of a object like
image or mesh. What happens, if you try your second suggestion?
How is your mesh generated?
