[Insight-users] pb with Versor3DRigidTransform

[Luis Ibanez]

Hi Vincent,

You can easily solve this problem by invoking the method

             transform->SetIdentity()

before you initialize the translation of the transform.


I assume that you are setting the translation by invoking
the method "Translate()", is this how you did it ?

Also... what version of ITK are you using ?

The Transform hierarchy was somehow refactored before
the release of ITK 2.2


   Please let us know


     Thanks


         Luis
