'''[[w:Bidirectional reflectance distribution function]]''' or '''BRDF''' is a 7D model containing geometry, textures and reflectance of the subject.
{{Q|The '''bidirectional reflectance distribution function''' ('''BRDF''') is a function of four real variables that defines how light is reflected at an [[w:Opacity (optics)|opaque]] surface. It is employed in the [[w:optics|optics]] of real-world light, in [[w:computer graphics|computer graphics]] algorithms, and in [[w:computer vision|computer vision]] algorithms.|Wikipedia|[[w:bidirectional reflectance distribution function|BRDF]]}}


The seven dimensions of the BRDF are as follows: 3 cartesian X,Y,Z and 2 for the entry angle and 2 for the exit angle of the light.
