Apr 18, 2024 · This paper introduces a new volumetric rendering algorithm that extends and adapts the previous \emph{path graph} surface rendering algorithm.

In path graph, we use an aggregation operator to gather incoming radiance from nearby shading points and recompute the outgoing radiance at the points. Then we ...

Abstract: In this paper we show how bidirectional path tracing can be extended to handle global illumination effects due to participating media.
