We extend them to allow dynamic volumetric visibility from area light sources using imperfect shadow volumes. We show a coarser visibility sampling suffices for area lights. Combining this coarser resolution with a parallel shadow volume construction enables interactive rendering of dynamic volumetric shadows from area lights in homogeneous single-scattering media, at under 4x the cost of hard volumetric shadows.CR CategoriesI.3.7 [Computer Graphics]Three Dimensional Graphics and RealismColorshadingshadowingtexture Keywordsshadowsarea lightsparticipating mediavoxelization10.1145/2492045.249205045-52
