Although, in the recent past, BRDFs have been extensively measured, compressed, and fitted by a variety of analytical models, most research has been primarily focused on simplified isotropic BRDFs. In this paper, we present a unique database of 150 BRDFs representing a wide range of materials; the majority exhibiting anisotropic behavior. Since time-consuming BRDF measurement represents a major obstacle in the digital material appearance reproduction pipeline, we tested several approaches estimating a very limited set of samples capable of high quality appearance reconstruction. Initially, we aligned all measured BRDFs according to the location of the anisotropic highlights. Then we propose an adaptive sampling method based on analysis of the measured BRDFs. For each BRDF, a unique sampling pattern was computed, given a predefined count of samples. Further, template-based methods are introduced based on reusing of the precomputed sampling patterns. action ARLID cav_un_auth*0307775 name Pacific Graphics 2014 dates 08.10.2014-10.10.2014 place Soul country KR RIV BD reportyear 2015 num_of_auth 2 mrcbC52 4 A 4a 20231122140508.7 inst_support RVO:67985556 permalink http://hdl.handle.net/11104/0238335 confidential S mrcbT16-e COMPUTERSCIENCESOFTWAREENGINEERING mrcbT16-j 1.237 mrcbT16-s 0.942 mrcbT16-4 Q1 mrcbT16-B 87.556 mrcbT16-C 83.173 mrcbT16-D Q1 mrcbT16-E Q1 arlyear 2014 mrcbTft \nSoubory v repozitáři: filip-0432894.pdf mrcbU14 84928468371 SCOPUS mrcbU34 000344369200010 WOS mrcbU56 hypertextový soubor PDF 15MB mrcbU63 cav_un_epca*0252549 Computer Graphics Forum 0167-7055 1467-8659 Roč. 33 č. 7 2014 91 99 Wiley
