The surface-integral form of radiative transfer equation is generalized to accommodate nonhomogeneous radiative properties for a multidimensional participating medium. A straightforward numerical quadrature scheme is then applied to solve the equation of transfer for test cases of radiation in an absorbing, emitting, anisotropic scattering, two-dimensional cylindrical medium with space- dependent radiative properties. To illustrate the effectiveness and accuracy of the approach, the product-integration method (PIM) is also used as a bench mark comparison in the numerical analysis. It is shown that consistent numerical predictions are obtainable by both schemes for the cases considered, whereas the computational efforts for the current method are much less than those requirred by the product-integration method.
