The general scattered light (GSL) model is a computer program for predicting the spectral radiant intensity and in-band spatial radiance image for objects embedded in a scene. It was developed by Aerodyne Research under a Small Business Innovation Research project. Its significant capabilities include general bidirectional reflectance distribution function (BRDF), angularly structured illumination, general first surface reflections (via BRDF), infinite-order diffuse higher order reflections, estimated radiance fidelity, and optimized algorithms for short run-times. The general approach to radiance modeling taken in GSL makes it well suited for accurate object and background radiance modeling. GSL even includes the SEABEAM sea surface radiance model from Nichols Research for maritime applications.
