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.
