Abstract
We present 3-dimensional radiative transfer models for clumpy dust tori around AGN. Our method combines Monte Carlo simulations of individual dust clouds with the actual 3-dimensional distribution of clouds in the torus. The model has been applied to NIR and MIR photometric and interferometric observations of NGC 1068. For the first time, it is possible to simultaneously reproduce both photometric and interferometric observations in the NIR and MIR. We infer a luminosity L = 2×1045 erg/s and an inclination of
 i = 70◦ for NGC 1068 from our model.
