We calculate accretion disk models around massive black holes. The effects of radiative pressure and self-gravitation on the disk structure are treated in a self-consistent way. To calculate the continuous energy distribution the radiative transfer equation is solved on a three dimensional spatial grid. Our results show that radiative pressure changes the disk structure drastically. Self-gravitation changes the vertical disk height for relatively large radii. We discuss the effects of inclination onto the Balmer jump and conclude that these effects must be included accurately to reproduce the observational data. It is also shown that electron scattering can change the Lyman edge The comparison with the observed continua shows that it is difficult to explain the constantly increasing flux for small wavelengths with a thin disk model.
