The dependence on viewing angle of the observed disk spectrum of geometrically and optically thick accretion disks around supermassive black holes in quasars is investigated. A model of radiation-supported thick disks is analyzed, and the emitted spectrum is computed as a function of the inclination angle. The radiation field along the rotation axis is greatly enhanced by the multiple scattering of photons off the walls of the inner, very hot and luminous, funnel-shaped region. It is found that the funnel dominates the emission from tori which are viewed more pole-on, i.e., at small viewing angles from the symmetry axis of the torus. This gives rise to a UV/soft X-ray thermal component. Tori viewed nearly edge-on, i.e., at large viewing angles from the symmetry axis, appear less luminous and cooler, possibly accounting for the optical/UV bump.
