/** \class VersorRigid3DTransform
 *
 * \brief VersorRigid3DTransform of a vector space (e.g. space coordinates)
 *
 * This transform applies a rotation and translation to the space
 * The parameters for this transform can be set either using individual Set
 * methods or in serialized form using SetParameters() and SetFixedParameters().
 *
 * The serialization of the optimizable parameters is an array of 6 elements.
 * The first 3 elements are the components of the versor representation
 * of 3D rotation. The last 3 parameters defines the translation in each
 * dimension.
 *
 * The serialization of the fixed parameters is an array of 3 elements defining
 * the center of rotation.
