WebBasically use a diffuse BRDF (lambert, oren nayar) if the material's refraction is scattering is less than 1 pixel. Use refraction and subsurface models if the scattering is larger than a pixel. I.e. in a glass refraction case the light exit is much greater than 1 … WebApr 18, 2008 · We present data on several types of expanded polystyrene, a common structural material for systems and experiments in this frequency range. In these measurements of BRDF, transmission agrees with previous measurements, and the balance between low and high angle scattering, specular reflectance, and absorption is …
