A Practical Microcylinder Appearance Model for Cloth Rendering

A practical shading model for rendering cloth that can simulate both anisotropic highlights and the complex color shifts seen in cloth made of different colored threads. The model is based on extensive Bidirectional Reflectance Distribution Function (BRDF) measurements of several cloth samples.

Acquiring Reflectance and Shape From Continuous Spherical Harmonic Illumination

A new reflectance measurement and 3D scanning technique uses a rotating arc of light and long-exposure photography to illuminate an object with spherical harmonic illumination and estimate maps from multiple viewpoints. The responses yield estimates of diffuse and specular reflectance parameters and 3D geometry.

Practical SVBRDF Capture in the Frequency Domain

This novel method to acquire the SVBRDF of near-planar objects using commodity hardware is the first to produce consistent normals and reflectance for both diffuse and specular surfaces using a pervasively available capture system.

OpenSurfaces: A Richly Annotated Catalog of Surface Appearance

OpenSurfaces is a large database of thousands of annotated surfaces created from real-world consumer photographs. Its annotation pipeline draws on crowdsourcing to segment surfaces from photos, and then annotates them with rich surface-appearance properties, including material, texture, and contextual information.
