ST-CVAE 305sFigure 1: Subsurface scattering simulation for homogeneous media with varying density and high anisotropy (g = 0.875) using standard path-tracing (PT) vs. our approach -a sphere-tracing algorithm using data-driven learning of multiple-scattering statistics (ST-CVAE). 8000 light paths per pixel are simulated. Density doubles from left to right, increasing the number of scatter events during path-tracing. Our approach achieves improved performance by summarizing long scattering chains into a single sphere-tracing step.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
