Abstract
The simulation of the transport of light through non-empty media is of
great importance in volume visualization applications. For low-albedo
media, the Single Scattering Model is a good approximation, and it is
used extensively. Its derivation is presented here in detail. The
model establishes the light that reaches an observer through a
participating media from a given direction. The resultant expression
is an integral of light contributions over a line of sight properly
scaled by their correspondent attenuation factors. In the general
case, the integral has not closed form solution. Some simplificative
assumptions that allow to compute it analytically are exposed
here. Finally, it is shown how the Single Scattering Model may be
applied both to ray-casting and to splatting algorithms, and how it is
used to shade surfaces in direct volume rendering.
