Ray tracing volume densities. This paper presents new algorithms to trace objects represented by densities within a volume grid, e.g. clouds, fog, flames, dust, particle systems. We develop the light scattering equations, discuss previous methods of solution, and present a new approximate solution to the full three-dimensional radiative ...

3.2 A ray tracing algorithm for the low albedo case In this section we will describe a new technique which allows one to ray trace volume densities without any viewing or lighting restrictions. But for one slight twist, this method is essentially a brute force develop- meat of the Blinn single scattering model for ray trac- ...

Sampling In the simplest case, choose our sample points at pixel centers For better results, can supersample – e.g., at corners and at center Even better techniques do adaptive sampling: increase sample density in areas of rapid change (in geometry or lighting) With stochastic sampling, samples are taken probabilistically; converges faster than regularly spaced sampling
