3D toroidal geometry (including shadowing) of a supercritical accretion disk (Model B). The structure is shown at inclination angles i = 45° (top) and i = 15° (bottom), with r and z expressed in units of r_S. The shadow boundary depends on both radius and azimuth (see Appendix A), and the resulting geometry produces pronounced anisotropy that exceeds the standard inclination–induced anisotropy of a thin accretion disk. The thick funnel extends out to ∼300 r_S where it is matched to an outer geometrically thin disk shown extending to r = 500 r_S to illustrate the geometric transition. The color coding represents the bolometric surface brightness of the accretion disk, where brighter (yellow) colors indicate regions of higher intensity and darker (blue) colors indicate lower intensity.
