Perceived quality of BRDF models

Computer Graphics Forum
AbstractMaterial appearance is commonly modeled with the Bidirectional Reflectance Distribution Functions (BRDFs), which need to trade accuracy for complexity and storage cost. To investigate the current practices of BRDF modeling, we collect the first high dynamic range stereoscopic video dataset that captures the perceived quality degradation with ...

In Praise of an Alternative BRDF Parametrization.

, 2015
In this paper, we extend the work of Neumann et al. [NNSK99] and Stark et al. [SAS05] to a pair of 4D BRDFparameterizations with explicit changes of variables. We detail their mathematical properties and relationships tothe commonly-used halfway/difference parametrization, and discuss their benefits and drawbacks using a few an-alytical test functions ...

ALTA: A BRDF Analysis Library.

, 2014
In this document, we introduce ALTA, a cross platform generic open-source library for Bidirectional Reflectance Distribution Function (BRDF) analysis. Among others, ALTA permits to estimate BRDF models parameters from measured data, to perform statistical analysis and also to export BRDF data models in a wide variety of formats.
