To those who are interested in materials rendering.

"The bidirectional reflectance distribution function (BRDF) formalism is commonly used in computer graphics to represent surface reflection properties. Although many BRDF models have been proposed, most do not possess at least some of the desirable practical properties. In this paper we present a simple and flexible model which satisfies many of these requirements. We show that the proposed model provides a good approximation for many real world materials, obeys basic physical restrictions, allows straightforward hardware implementation and provides for efficient sampling in a Monte-Carlo rendering system. A procedure to fit the model to BRDF measurement data is presented which suggests a simplified way of measuring surface reflection. "

It's very unusual to post some research paper , but this one , I feel, is very important. Quite unfortunate that Ashikhmin left the graphics world since his research contributions are pretty cool. I hope he is working for some big VFX company working on new material rendering.
