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

[Aya El Gebeely]

Thanks Michael,

I just do not know how to use the versor to get from it the Rotation
matrix..

after transformation is done, we can get the versor through:
transform->GetVersor()

but after this, how to get the rotation Matrix ... excuse me, but my
knowledge in this part is limited

Appreciating your kind help,
Aya
