Abstract

The BEAMS (battlefield emission and multiple scattering) model is a 26-stream radiative transfer algorithm for the prediction of diffuse radiance in finite 3D non-uniform aerosol clouds. It has been developed by the US Army Research Laboratory as a visualization tool that satisfies the need for visual simulations to show realistic variation of a cloud with varying viewing angle, cloud geometry, optical depth, and external incident radiation.Uses of this high fidelity model for simulating propagation effects in a realistic 3D terrain environment are shown. Examples are shown in the visible wavelength for both daytime scenarios and nighttime scenarios (where the cloud is artificially illuminated by flares). Other examples are shown for infrared wavelengths, which use the GTSIMS model for terrain radiance prediction. Performance issues of cloud rendering are also discussed, including modeling the cloud with performer billboards on the silicon graphics computers.
