Paper Abstract
The TETRA bi-directional reflectance distribution function (BRDF) model was developed to simulate the reflection
from random rough surfaces in optical radiation transfer modeling by the Monte Carlo method (MCM). This procedural
model is based on geometrical optics, has as a prototype the two-dimensional model proposed by Torrance and Sparrow,
and allows generating, for each ray, a random tetrahedral pit with walls that reflect according to Fresnel's law. An
incident ray undergoes one or several reflections from the tetrahedron's walls, and then continues to participate in the
radiation transfer on the macro-level. The properties of the TETRA BRDF are studied using numerical experiments.
