Abstract. We present a new 2D ray-tracing technique for computing the emergent spectra of winds originating from the surfaces of primary star and accretion disk in cataclysmic binaries. By using a highlymodular approach, allowing easymodification and extension of the code, we self-consistently solve the pan-chromatic radiative transfer problem in moving media. Primary application of this code is to complement and to be used in conjunction with model atmosphere codes for stellar and accretion disk atmospheres and wind hydrodynamical models.
