Although production volume rendering has been well studied over the past decade, there are still some volumetric features that cannot be rendered with the latest methods. In particular, when rendering fire or explosion volumes, current state-of-the-art techniques lack refraction effects due to temperature or pressure changes and are especially problematic when using next event estimation. In this talk, we present two unbiased volume rendering algorithms that
can achieve a wide range of refractive effects, such as heat haze, blast waves and caustics. We demonstrate on a set of test scenes that these new features significantly improve the visual appearance of these volumes.
