描述了一种能够处理各向异性散射介质中任意表面排列的三维辐射传递几何光学模型。该模型将曲面和体积离散为块和体素，并建立每对元素之间的辐射传递关系。在平面平行结构下，定向辐射的计算结果与数值积分不变嵌入法基本一致。结合表面水波和复杂底栖生物结构的两个实例，采用能量守恒法对模型精度进行了评估，误差小于1%。阐述了在浅水环境中结构复杂的底栖生物的遥感或光生物学研究中的潜在应用。
A geometric optical model for three-dimensional radiative transfer capable of handling arbitrary arrangements of surfaces within anisotropic scattering media is described. The model operates by discretizing surfaces and volumes into patches and voxels and establishing the radiative transfer relationship between every pair of elements. In a plane-parallel configuration results for directional radiance agree closely with the numerical integration invariant imbedded method. Model accuracy for two examples incorporating surface water waves and complex benthic structures were assessed by conservation of energy, errors were less than 1%. Potential applications in remote sensing or photobiological studies of structurally complex benthos in shallow water environments are illustrated.
