At the microscopic scale, feather appearance is dictated by the anisotropic behavior of directional feather parts. At the nanoscale, some species exhibit structural color due to light diffraction on structures comparable in size to the wavelength of light. In this paper, we capture feathers from four different species, analyze various aspects of their appearance, and suggest its efficient modeling approach. cav_un_auth*0472332 CVCS2024: the 12th Colour and Visual Computing Symposium 20240905 20240906 Gjøvik NO BD 20000 20200 20201 2025 3 PR RVO:67985556 https://hdl.handle.net/11104/0356117 1 S 0.202 Q4 2024 85206391104 SCOPUS PUBMED WOS PDF 2 MB cav_un_epca*0598135 CEUR Workshop Proceedings : CVCS2024- the 12th Colour and Visual Computing Symposium CEUR-WS 2024 Aachen CEUR Workshop Proceedings 3766 1613-0073
