''' | {{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 | A BRDF model is a 7 dimensional model containing geometry, textures and reflectance of the subject. | ||
The seven dimensions of the BRDF are as follows: | |||

* 2 for the entry angle | |||
* 2 for the exit angle of the light. | |||
