Hi David,

Let me see if I get:

a) set the two known points ( the points on each cap of the cylinder )
to source of the vtkLandmarkTransform ( SetSourceLandmarks )
b) set the two desired points to target of the vtkLandmarkTransform (
SetTargedLandmarks )
c) set a type of transform ( rigid? )
d) creates a vtkTransformPolyDataFilter and sets the previous
vtkLandmarkTransform to this filter
e) apply the filter on the polydata

That's it?
