Ongoing research in BRDF’s seeks to:
•Recover BRDF’s from “just a few” images, model global light transport
–Yu, Debevec, Malik and Hawkins, “Inverse Global Illumination”, SIGGRAPH 1999.
•Model semi-transparent, refractive surfaces
–Zongker, Werner, Curless, and Salesin, “Environment Matting and Compositing”, SIGGRAPH 99, pp. 205-214.
•Model sub-surface scattering
–Jensen, Marschner, Levoy and Hanrahan: “A Practical Model for Subsurface Light Transport”, SIGGRAPH'2001.
