The interaction of light and matter in the world surrounding us is of striking complexity and
beauty. Since the very beginning of computer graphics, adequate modelling of these …

Research on neural radiance fields (NeRFs) for novel view generation is exploding with new
models and extensions. However, a question that remains unanswered is what happens in …

It is a long-standing problem in unbiased Monte Carlo methods for rendering that certain
difficult types of light transport paths, particularly those involving viewing and illumination …

Translucent materials are ubiquitous, and simulating their appearance requires accurate
physical parameters. However, physically-accurate parameters for scattering materials are …

We present two contributions to the area of volumetric rendering. We develop a novel,
comprehensive theory of volumetric radiance estimation that leads to several new insights …

Complex specular surfaces under sharp point lighting show a fascinating glinty appearance,
but rendering it is an unsolved problem. Using Monte Carlo pixel sampling for this purpose …

Scattering from specular surfaces produces complex optical effects that are frequently
encountered in realistic scenes: intricate caustics due to focused reflection, multiple …

We propose a novel system for designing and manufacturing surfaces that produce desired
caustic images when illuminated by a light source. Our system is based on a nonnegative …

Participating media are frequent in real-world scenes, whether they contain milk, fruit juice,
oil, or muddy water in a river or the ocean. Incoming light interacts with these participating …

Real-world materials are often layered: metallic paints, biological tissues, and many more.
Variation in the interface and volumetric scattering properties of the layers leads to a rich …
