It seems like an implementation of the method of Alessandro Frangi et
al, maybe you could get a look on his publications.
So yes, it is possible!

Once your reference volume is transformed into a mesh, you might want to
decimate it so as to consider the remaining points, supposedly
representative of the shape geometry, as decent "landmarks" points,
though the works of Davies et al. shows the limits of "easy" landmarking
approaches.
You can edit the vtk file at this stage to retrieve coordinates of the
points/landmarks, but you actually needn't since VTK provides (probably)
all functionalities required for a PCA analysis.

So, you might now want to make a training set with the other volumes in
propagating the landmarks from the reference... Maybe ITK or VTK can
perform volume registration, but tools such as AIR (Roger Woods) do it
also. At least, it can save volume to volume registration parameters in
a file, and then apply it to a file of points, giving what you might
want.


But maybe you can tell us more details about what you actually want to
do?
