<p class="MsoNormal">Hello, <o:p></o:p></p>
<div>
<p class="MsoNormal">I'm hoping someone has a reference that will allow me to convert from a 3X3 rotation matrix to a 3-member versor rotation for the purposes of setting a known rotation about one axis as an initialization. For instance, if I wanted the equivalent
of a 10 degree rotation about the x-axis, I can build a 3X3 rotation matrix using sines and cosines, but the project I'm working on is using VersorRigid3DTransform as the transform type for the registration, so I'd like to use that for the initial transform.<o:p></o:p></p>
