The interaction between light and materials is key to physically-based realistic rendering.
However, it is also complex to analyze, especially when the materials contain a large …

Physically based rendering of complex scenes can be prohibitively costly with a potentially
unbounded and uneven distribution of complexity across the rendered image. The goal of …

Tremendous effort has been extended by the computer graphics community to advance the
level of realism of material appearance reproduction by incorporating increasingly more …

We consider the problem of multiple scattering on Smith microfacets. This problem is
equivalent to computing volumetric light transport in a homogeneous slab. Although the …

Most models for bidirectional surface scattering by arbitrary explicitly defined microgeometry
are either based on geometric optics and include multiple scattering but no diffraction effects …

This document provides additional derivations concerning integration and sampling of GGX
distribution on polygonal domains, building up to C++ fragments. We also include a brief …

Physically based rendering of glittering surfaces is a challenging problem in computer
graphics. Several methods have proposed off‐line solutions, but none is dedicated to high …

Normal map‐based microstructure rendering can generate both glint and scratch
appearance accurately. However, the extra high‐resolution normal map that defines every …

We propose an importance sampling scheme for the procedural glittering BSDF of Chermain
et al.[CSDD20]. Glittering BSDFs have multi-lobe visible normal distribution functions …

The glinty details from complex microstructures significantly enhance rendering realism.
However, the previous methods use high-resolution normal maps to define each micro …
