This dataset contains the Bidirectional Reflectance Distribution Functions (BRDFs) related to the study presented in the reference below.

Guillaume Lavoué, Nicolas Bonneel, Jean-Philippe Farrugia, Cyril Soler, Perceptual Quality of BRDF Approximations: Dataset and Metrics, Computer Graphics Forum (Eurographics 2021), May 2021. 

The dataset consists in 100 source BRDFs (from the MERL-MIT BRDF database), subject to approximations with different models, producing a total of 2026 BRDFs (including references). The dataset is provided in two formats: the standard MERL binary format and our own TITOPO format.
