Monte Carlo calculations for axial symmetric, scattering dominated photospheres have been performed in order to study systematically the effects due to the direction dependent luminosity and to reinvestigate the continuum polarization in SN 1987A (Mendez et al. 1988). We found that the optical depth and the occultation effects are important for the interpretation of the observed polarization, and that the differences between the electron and the density profile are substantial for the understanding of the observed time dependence of the linear polarization in SN 1987A. The observed polarization can be well understood by prolate or oblate ellipsoids (a/b = 0.9 or 1.2) if SN 1987A is seen at an inclination angle of less than 56^deg^ with a most probable value of about 40^deg^.
