Aims. We extend our framework for 3D radiative transfer calculations with a non-local operator splitting methods along (full) charac-teristics to spherical and cylindrical coordinate systems. These coordinate systems are better suited to a number of physical problemsthan Cartesian coordinates.Methods. The scattering problem for line transfer is solved via means of an operator splitting (OS) technique. The formal solution isbased on a full characteristics method. The approximate A operator is constructed considering nearest neighbors exactly. The code isparallelized over both wavelength and solid angle using the MPI library.Results. We present the results of several test cases with different values of the thermalization parameter for the different coor-dinate systems. The results are directly compared to 1D plane parallel tests. The 3D results agree very well with the well-testedI D calculations.Conclusions. Advances in modern computers will make realistic 3D radiative transfer calculations possible in the near future.
