Material properties are an important ingredient for rendered virtual scenes.
Besides lighting and geometry, the material properties (e.g. wood vs. metal)
have a strong visual effect on the final image. The BRDF is a mathematical
formalization of many common materials, and is used as input to most
rendering engines. Choosing parameters for a BRDF has traditionally been a
trial-and-error process with a large lag between results. In this talk, I
present my work on real-time BRDF editing to enable interactive material
design. I will show how we can formulate the problem of editing a BRDF as a
precomputation problem. Complex lighting and geometry are handled without
slowing down the rendering process, thus allowing artists and designers to
interactivley see the affects of their choices as they edit the BRDF of
objects in a virtual scene.


Aner Ben-Artzi is currently in his 5th (and final) year as a PhD student at
Columbia University’s C2G2 lab for Computer Graphics. He received his BA in
Computer Science at UC Berkeley, and MS at Columbia University. His focus
has been on real-time photorealisic rendering, with an emphasis on material
