synthesis is the process of computing images that are
perceptually indistinguishable from the real-world they are
attempting to portray. Such a level of fidelity requires that
the physical processes of materials and the behavior of light
are accurately simulated. Most computer graphics algorithms
assume that light passes freely between surfaces within an
environment. However, in many applications we also need to take
into account how the light interacts with media, such as dust,
smoke, fog etc, between the surfaces. The computational
requirements for calculating the interaction of light with such
participating media are substantial. This process can take many
hours and rendering effort is often spent on computing parts o
