Comparison of microfacet BRDF model elements to diffraction BRDF model elements

, 2015
A popular class of BRDF models is the microfacet model, where geometric optics is assumed, but where physical optics effects such as accurate wavelength scaling, important to Hyperspectral Imagery, are lost.

A Neural Quality Metric for BRDF Models

Accurately evaluating the quality of bidirectional reflectance distribution function (BRDF) models is essential for photo-realistic rendering. Traditional BRDF-space metrics often employ numerical error measures that fail to capture perceptual ...

Evaluation of MODIS and VIIRS BRDF Parameter Differences and Their Impacts on the Derived Indices

Remote Sensing
Multi-angle remote sensing observations play an important role in the remote sensing of solar radiation absorbed by land surfaces. Currently, the Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS ...

BRDF and gloss measurements

, 2007
Gloss is an important aspect of our visual perception of objects. Many developments of gloss measurement have been carried out as part of the technical work of the ASTM, resulting in the ASTM method D523.

Deep Image-Based Adaptive BRDF Measure

Efficient and accurate measurement of the bi-directional reflectance distribution function (BRDF) plays a key role in realistic image rendering. However, obtaining the reflectance properties of a material is both time-consuming and challenging.

Isotropic BRDF Measurements with Quantified Uncertainties

, 2016
Image-based BRDF measurements on spherical material samples present a great opportunity to shorten significantly the acquisition time with respect to more traditional, non-multiplexed measurement methods for isotropic BRDFs.

VMF Diffuse: A Unified Rough Diffuse BRDF

We present a practical analytic BRDF that approximates scattering from a generalized microfacet volume with a von Mises- Fischer NDF. Our BRDF seamlessly blends from smooth Lambertian, through moderately rough height fields with Beckmannlike statistics ...

Generating Reflected Directions from BRDF Data

, 1997
Monte-Carlo path tracing algorithms for computer graphics require that given an incident light ray at a surface an outgoing direction can be computed with a distribution given by the magnitude of the bidirectional reflectance distribution function (BRDF).
