Innovations in Fur Shader and Shadow Algorithms: Insights from SIGGRAPH ASIA 2023

This presentation highlights key advancements showcased by Valentin Janiaut from KAIST at SIGGRAPH ASIA. It covers an empirical fur shader developed for Square Enix, a point-based hair global illumination technique, and introduces a hierarchical volumetric shadow algorithm tailored for single scattering. Furthermore, it discusses scattered data interpolation methods in computer graphics and proposes a new scattering model for animal fur representation using Unicube maps. The presentation also explores epipolar correction applications in shadow mapping.

Presentation Transcript

  1. Back from SIGGRAPH ASIA Valentin JANIAUT KAIST (Korea Advanced Institute of Science and Technology)

  2. Some interesting things • Technical Sketches • An Empirical Fur Shader (Square Enix) • Point Based Hair Global Illumination • Technical Paper • A Hierarchical Volumetric Shadow Algorithm for Single Scattering (Ilya Baran) • Course • Scattered Data Interpolation for Computer Graphics

  3. An Empirical Fur Shader • Propose a new scattering model for animal fur fiber. Representation in Unicube map.

  4. Point based Hair Global Illumination • No PDF …

  5. A Hierarchical Volumetric Shadow Algorithm for Single Scattering • Use an epipolar correction to determine the useless sample. • Could we do the same with the Deep Opacity Shadow Map from [Yuksel08] ?
