An approach to the solution of radiative-transfer problems in multidimensional atmospheres is introduced which is a generalization of Rybicki's (1971) core-saturation method. A computer program is outlined which consists of nearly independent radiative-transfer and geometric or atmospheric routines and which assumes a two-level atom, complete redistribution, and a Gaussian line profile. A local convergence criterion is given, and the program is tested by computing line-source functions for cylinders with varying radial optical depth, a collisional thermalization parameter of 0.0001, and a Planck function of unity. Very good agreement is indicated between the results obtained and those of previous calculations.
