What Does BRDF Stand For?

BRDF stands for Bidirectional Reflectance Distribution Function

BRDF, or Bidirectional Reflectance Distribution Function, is a fundamental concept in the field of optics and remote sensing. It characterizes how light is reflected off a surface by defining the relationship between incoming and outgoing light directions. Specifically, BRDF quantifies the amount of light reflected by a surface as a function of the angle of incidence and the angle of reflection, providing essential information for various applications, including computer graphics, environmental monitoring, and material analysis.
