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 …

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

Creating an appearance-preserving level-of-detail (LoD) representation for arbitrary 3D
scenes is a challenging problem. The appearance of a scene is an intricate combination of …

The 3D visual optical arts can produce impressive special effects by designing interactions
between objects and light sources, displaying images in shadows, caustics, or reflectors …

High-performance ray tracing of triangle meshes equipped with displacement maps is a
challenging task. Existing methods either rely on pre-tessellation, taking full advantage of …

The detailed glinty appearance from complex surface microstructures enhances the level of
realism but is both-and time-consuming to render, especially when viewed from far away …

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 …

Measured Bidirectional Texture Function (BTF) can faithfully reproduce a realistic
appearance but is costly to acquire and store due to its 6D nature (2D spatial and 4D …

Multi-layered materials are layered structures of composing anisotropic media where each
layer may have a separate scattering behavior. Multi-layered materials are widely used in …

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