The required material representations depend on the complexity of the material's appearance. They start with a bidirectional reflectance distribution function (BRDF) describing distribution of energy reflected in the viewing direction when illuminated from a specific direction. As the BRDF cannot capture a material's spatial structure, it has been extended to a more general bidirectional texture function (BTF) capturing non-local effects in rough material structures, such as occlusions, masking, sub-surface scattering, or inter-reflections. A monospectral BTF is a six-dimensional function representing the material appearance at each surface point for variable illumination and view directions, parameterized by elevation and azimuthal angles. This paper describes application of gonioreflectometrs for capturing BTF for material visualization purposes. cav_un_auth*0333107 The 4th CIE Expert Symposium on Colour and Visual Appearance 06.09.2016-07.09.2016 Praha CZ BD 2017 3 PR RVO:67985556 http://hdl.handle.net/11104/0262341 S 2016 hypertextový soubor PDF 2MB cav_un_epca*0462361 Proceedings of the 4th CIE Expert Symposium on Colour and Visual Appearance 978-3-902842-59-6 121 127 Vienna Commission Internationale de L'Eclairage CIE Central Bureau 2016
