  abstract =   "Under certain circumstances the polarisation state of the
               illumination can have a significant influence on the
               appearance of scenes; outdoor scenes with specular surfaces
               -- such as water bodies or windows -- under clear, blue
               skies are good examples of such environments. In cases like
               that it can be essential to use a polarising renderer if a
               true prediction of nature is intended, but so far no
               polarising skylight models have been presented.    This
               paper presents a plausible analytical model for the
               polarisation of the light emitted from a clear sky. Our
               approach is based on a suitable combination of several
               components with well-known characteristics, and yields
               acceptable results in considerably less time than an
               exhaustive simulation of the underlying atmospheric
               scattering phenomena would require.",
