The technique described above is a novel method for simulating the illumination of atmospheric phenomena. Due to its scalability, and with the help of massively parallel computers that are rapidly becoming faster and having larger memories, the technique should become practical for a variety of illumination problems in the near future.
A logical extension of the algorithm is the coupling of a hierachy of multiply scattering volumes that allow one to control the level of detail of the rendering. For example, it may be possible to illuminate a larger volume with an interior subsampled volume included, then use the resulting steady light solution as the boundary condition with which to illuminate the interior model sampled at a higher resolution (perhaps even feeding into a radiosity renderer). The resulting volume hierachy may then have view dependant solutions extracted with far more detailed interior objects e.g. low level clouds.
