[Insight-users] Affine vs versorrigid3dtransform

[Xabier Artaechevarria Artieda]

Hi Trevor,
the answer to your questions is in pages 403 and 407 of the Software  
Guide. In fact, VersorRigid3DTransform considers a 3D translation and  
a 3D rotation. The Affine transform also includes scaling and shearing.
Regards,
Xabi
