ABSTRACT
The capabilities and visual quality of real-time rendered volumetric effects disproportionately lag those of film. Many other real-time rendering categories have seen recent dramatic improvements. Lighting, shadowing, and postprocessing have come a long way in just the past few years. Now, volumetric rendering is ripe for a transformation. We now have enough compute to build practical implementations that approximate film-style effects in real time. This chapter presents one such approach.
