Abstract

Two well-known examples of physically plausible BRDF models are the Fresnel reflectance and Torrance-Sparrow models. They describe the surface reflectance behavior down to its reflective polarization properties.

To verify the accuracy of these physically based models, we collected a set of metallic surfaces. Then, we used an ellipsometer to measure the polarization properties of their reflected light.

Finally, we compared the measurements to the reflectances we predicted from the physically plausible BRDF models.
