- July 1, 2015Mitsuba renderer and ALTA Library now support our BRDF database.
- October 8, 2014Database of 150 anisotropic BRDFs released.
- April 14, 2014Dense BRDFs of three anisotropic fabrics added (angular resolution 2o).
- April 10, 2013Dense BRDF measurements of fabric02 added (angular resolution 0.5o).
UTIA BTF database is a new source of publicly available Bidirectional Texture Function (BTF) and Bidirectional Reflectance Distribution function (BRDF) measurements. As accurate acquisition and processing of BTF data is expensive, time and resource demanding there is a lack of publicly available BTF/BRDF datasets for research purposes.
Our motivation is to support correct material appearance modelling research by offering several novel high-resolution HDR datasets.
The UTIA BTF database is gradually expanding. Your possible measurement suggestions are welcomed.
