Hello,
If this is the example you are using[1], while its in the RegistrationITKv4 directory \
it is using the ITKv3 version of the framework.
If you compare it to the MultiResImageRegistration1.cxx example, its significantly \
more complicated. With the ITKv4 framework its an intrinsic part of the registration \
method. I would encourage you to base your registration program on example 1 and \
modify it for 3D.
You are right about the TranslationTransform not working with that Initializer. But \
it does work with any transform derived from the MatrixOffsetBase.
