We analyzed 2D BRDF subspaces of eleven materials. We compared performance of five interpolation methods, three different sampling patterns, and compared twelve adaptive sampling strategies. Finally, based on knowledge of entire data we estimated sub-optimal sampling patterns and as a reference compared them with other tested sampling approaches. 2014 BD 4 O 4o 20231122140056.7 RVO:67985556 http://hdl.handle.net/11104/0230618 2013 Soubory v repozitáři: 0424346.pdf 2013 Praha ÚTIA AV ČR 10MB
