Path-Space Manipulation of Physically Based Light Transport

A light transport manipulation that operates directly on the path-space of full global illumination solutions for plausible editing shading effects such as caustics, diffuse/glossy indirect illumination, and shadows. Also: selection and visualization tools to inspect and isolate lighting effects.

Interactive Albedo Editing in Path‐Traced Volumetric Materials

This editing algorithm for setting the local (single‐scattering) albedo coefficients of a dense volume interactively produces an immediate update of the emergent appearance in the image.

Global Illumination With Radiance Regression Functions

Radiance regression functions (RRF) for fast rendering of global illumination in scenes with dynamic local light sources. A radiance regression function represents a non-linear mapping from local and contextual attributes of surface points, such as position, viewpoint, and lighting condition, to their indirect illumination values.

Modular Flux Transfer: Efficient Rendering of High-Resolution Volumes With Repeated Structures

A precomputation-based approach to accelerate renderings of very complex and highly scattering materials built from a small set of exemplars. The algorithm separates low-order and high-order scatterings and approximates the latter, which is usually smooth but expensive to compute, using a modular flux-transfer framework.
