Most applications rely on isotropic BRDFs due to their better availability as a result of their easier acquisition process. On the other hand, anisotropic BRDF due to their structure-dependent anisotropic highlights, are more challenging to measure and process. This paper describes approaches to BRDF analysis and acquisition using ellipsoidal and parabolic reflectors commonly used for in illumination industry. First, we show how reflectors can be used for detection of anisotropic properties as anisotropic axes and highlight width. Second, we outline and approach for anisotropic BRDF capture using reflector that allows fast and convenient measurement without need of measured sample extraction. cav_un_auth*0333107 The 4th CIE Expert Symposium on Colour and Visual Appearance 06.09.2016-07.09.2016 Praha CZ BD 2017 2 PR RVO:67985556 http://hdl.handle.net/11104/0262343 S 2016 hypertextový soubor PDF 2MB cav_un_epca*0462361 Proceedings of the 4th CIE Expert Symposium on Colour and Visual Appearance 978-3-902842-59-6 155 162 Vienna Commission Internationale de L'Eclairage CIE Central Bureau 2016
