[vtkusers] transformation matrix

[Goodwin Lawlor]

Hi Lena,
If your two skulls have corresponding points use vtkLandmarkTransform. If
not use vtkIterativeClosestPointTransform. If you want to align a set of
skulls then use vtkProcrustesAlignmentFilter.

Hi All!

Guess you have heard this question before, but I need at least to know, how
to start or which classes to use.

I have a PolyData (skull) and another PolyData, consisting only of points.
What I need is the 4x4 transformation matrix from one to another. Then I
should be able to transform the points, so they match best to the skull
model.

Hope it's enough information  to answer.

Lena
