[Insight-users] Simple question

[Yu Qi]

This code is from the ITKGuide,Rigid Transform in 3D
 
*******************************************************
typedef TransformType::VersorType VersorType;
typedef VersorType::VectorType VectorType;
VersorType rotation;
VectorType axis;
axis[0] = 0.0;
axis[1] = 0.0;
axis[2] = 1.0;
const double angle = 0;
rotation.Set( axis, angle );
transform->SetRotation( rotation );
*******************************************************
I want to know what  the variable  axis,angle are.
And why give them those values?
 
 
 



Best Regards!
