[Insight-users] How to get Transformation Matrix from VersorRigid3DTransform

[Luis Ibanez]

Hi Aya,

Please read the documentation of the itk::Versor class:

http://www.itk.org/Doxygen/html/classitk_1_1Versor.html

You will find useful the method:

                MatrixType  GetMatrix (void) const


    Regards,


             Luis
