[vtkusers] How to cut and flat a volumedata with an spline

[Bill Lorensen]

BTW, this is sometimes called curvilinear reformatting. It is
available on most commercial radiology workstations and many
commercial PACS systems. A google search on "curvilinear reformat"
will show you many papers and examples.
