Figures 6 and 7 show visualizations of the results for 3D continuum transfer. The RT problem was solved for $\epsilon=1$ (left panels) and $10^{-2}$ (right panels) and a formal solution with the converged source functions was computed for given viewing angles. The graphs are actual images of the intensities as they would be seen by an external observer different angles. The visible surface is to the left, the 'sides' of the computational box could not be seen by an observer and are shown for information only. The effect of scattering on the images is similar to terrestrial fog in that it reduces the contrast of visible features; even moderate scattering of $\epsilon_c=10^{-2}$ significantly reduces visibility. The limb darkening is also clearly visible in the figures.

Figures 9 to 12 show images generated for the results of the line transfer solution. Three panels show results for individual wavelength (continuum, line wing and line center) and a composite image. The images are significantly different for these wavelengths. The line scattering produces a similar 'fog effect' as the scattering in the continuum transfer model, however, the images appear not that different. While one might expect that the line images would look vastly different from the continuum visualization, part of the similarity is due to the fact that they were scaled individually in order to highlight the differences in structure between the wavelengths rather than comparing them on a absolute scale. The composite image (best viewed in color available in the online version of this paper) shows the differences in the visible structures between the different wavelengths.
