Description

The UBO 2014 consists of 7 semantic categories. Each of these 7 material categories contains measurements of 12 different material instances for being capable to represent the corresponding intra-class variances. Per material sample, a full BTF has been measured using the bi-directional sampling of 151 viewing directions and 151 lighting directions. Consequently, a total of 22,801 images have been acquired for material samples with a size of 5 cm x 5 cm with spatial resolution of 512 x 512 texels. The available BTFs contain the central 400 x 400 texels (corresponding to an area of approx. 3.9 cm x 3.9 cm).
