[Insight-users] Question about Versor, Matrix, final translation and offset

[Luis Ibanez]

Hi Yu,

It is all related to the fact that you can specify a
center of rotation.

This is explained in detail in the ITK Software Guide.

   http://www.itk.org/ItkSoftwareGuide-2.0.1.pdf

Section 8.8, pdf-pages 371 to 381. Look in particular
to section 8.8.11 in page 380.


  Regards,


     Luis
