Euclidean rotations in are bijective and isometric maps. Nevertheless, they lose these properties when digitized in . For , the subset of bijective digitized rotations has been described explicitly by Nouvel and Rémila and more recently by Roussillon and Cœurjolly. In the case of 3D digitized rotations, the same characterization has remained an open problem. We have been studied the problem and up-to-date, we have propose an algorithm for certifying the bijectivity of 3D digitized rational rotations using the arithmetic properties of the Lipschitz quaternions.
