[ITK-users] [ITK] SetCenter() example for VersorRigid3DTransform

[Andrew Harris]

Hello,
I'm trying to set the center of rotation for a VersorRigid3DTransform to
the middle of a 3D image in two dimensions and the top in the third. I
have as of yet been unable to find an example in the wiki of doing this.
The only example I've found appears to use a CenteredTransformInitializer
to set the center of rotation to the center of the image. Is there an
example of setting the center elsewhere, or if not, can someone provide me
the syntax I would use?

Hello,

You could use :
itk::OptimizerParameters<double> NewCenter(3);
NewCenter[0]=X;
NewCenter[1]=Y;
NewCenter[2]=Z;
MyTransform->SetFixedParameters(NewCenter);

or

itk::Point<double,3> NewCenter;
NewCenter[0]=X;
NewCenter[1]=Y;
NewCenter[2]=Z;
MyTransform->SetCenter(NewCenter);

I've mostly used the first way, but the second should work also I think.

HTH

Tim,
