This paper proposes a process for three-dimensional modeling of a target environment observed from the upper hemisphere. Generalized models of the radiance-factor patterns of elements of the surfaces being modeled are used for this, based on photometric parameters measured in the form of three components: a uniformly scattered component, a backscattered component, and a salient component oriented in the direction of specular reflection. These models are provided by a database of starting parameters that make it possible to reproduce radiance fields of specified target scenes as the ambient conditions change (during a day, from season to season, etc.). An example is given of modeling a scene that contains objects, buildings, various soils, plant cover, and a water surface.
