Microfacet distribution function for physically based bidirectional reflectance distribution functions
Abstract
A microfacet distribution function is presented. This function can be used to calculate the microfacet distribution term in BRDF models. The function differs from other wellknown microfacet distribution functions like Blinn or Beckmann distributions in that it doesn`t use special functions like acos, tan, exp, pow and thus has lower computational complexity.
