/** \class Similarity3DTransform
* \brief Similarity3DTransform of a vector space (e.g. space coordinates)
*
* This transform applies a rotation, translation and isotropic scaling 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 7 elements.
* The first 3 elements are the components of the versor representation
* of 3D rotation. The next 3 parameters defines the translation in each
* dimension. The last parameter defines the isotropic scaling.
*
* The serialization of the fixed parameters is an array of 3 elements defining
* the center of rotation.
