The '''visual appearance''' of objects is given by the way in which they reflect and transmit [[light]]. The [[color]] of objects is determined by the parts of the [[spectrum]] of (incident white) light that are reflected or transmitted without being absorbed. Additional appearance attributes are based on the directional distribution of reflected ([[BDRF]]) or transmitted light (BTDF) described by attributes like [[Gloss (material appearance)|glossy]], shiny versus dull, matte, clear, [[turbidity|turbid]], distinct, etc..
