将计算有参与介质时辐射传输的分区方法应用于真实感合成图像的生成。该方法概括了辐射度方法，并允许参与介质的发射、散射和吸收。分区法考虑了先前未包括的体积/表面相互作用，以及体积/体积和表面/表面相互作用。此外，新的算法，半立方体配方的基础上，介绍了计算所需的分区方法的几何因子。
The zonal method for calculating radiative transfer in the presence of a participating medium is applied to the generation of realistic synthetic images. The method generalizes the radiosity method and allows for emission, scattering, and absorption by a participating medium. The zonal method accounts for volume/surface interactions which have not been previously included, as well as volume/volume and surface/surface interactions. In addition, new algorithms, based on the hemi-cube formulation, are introduced for calculating the geometric factors required by the zonal method.
