[Insight-users] itk transform apply to vtk polydata

[flavio]

hi
I wrote e MR registration program, between two mri, that return a 
versorRigid3DTransform.trf.
I want to use this transform to move a geometric object associeted with 
the registration's moving image and display it with vtk but I don't 
understand how to convert itk
transfom to vtk coordinate system.
How I should use rotation(get with GetMatrix) and translation  in order 
to have the right position in vtk space?

thanks a lot
