The BRDF( Bidirectional Reflectance

The BRDF( Bidirectional Reflectance Distribution Function.) is a function that describes the ratio of the differential radiance reflected and the differential irradiance incident at any point on a hemispherical coordinate [1]. A BRDF itself has many attributes. For example, Helmholtz Reciprocity: the incident and excitant are interchangeable and have an unchanged value of BRDF, or Energy Conservation: the existence radiance is not more than incident radiance. Moore [2] proposed the first BRDF model based on a Microfacet theory. Otherwise, the model can only be used with an isotropic material. A BRDF model of [3] was developed based on the BRDF model [4] However, their shading model is not physically plausible and didn’t normalize a Microfacet distribution function. Phong [5] proposed a Microfacet BRDF framework which was further developed by [6]. However, it is not physically plausible because they ignored the cosθh term. Later, a halfway vector model disk was used in shading modeling by [7]. However, this shading ignores reciprocity. Currently, Kurt [8] proposed a Microfacet BRDF model that can be used in both isotropic and anisotropic materials. Their shading model is based on physical plausibility. Equation 1 is a BRDF equation
