Innovative and Versatile New Toolset Unveiled at SIGGRAPH
Takes Viewing BRDFs to New Levels of Accuracy and Efficiency
BURBANK, Calif. (Aug. 8, 2012) — Walt Disney Animation Studios (WDAS) is making its breakthrough BRDF Explorer available to the industry through a new open source site, it was announced August 7, 2012, at SIGGRAPH in Los Angeles by Brent Burley, the project’s principal engineer from WDAS software group. Burley, who gave a presentation at Tuesday’s conference on Disney’s proprietary approach to creating physically-based BRDFs (Bidirectional Reflectance Distribution Function, the mathematical description of how a surface reflects light), created the BRDF Explorer with his Disney colleagues Greg Nichols and Jared Johnson. He is a key player on the software team managed by Dan Candela, director of technology for WDAS.
Disney’s BRDF Explorer is an advanced physically-based shading and rendering toolset that evaluates BRDFs (a four-dimensional function that defines how light is reflected at an opaque surface) and how they compare to real life. It is capable of exploring the MERL 100 (Mitsubishi’s set of empirically measured data) and MIT CSAIL data sets, along with programmatic BRDF functions that can be defined by the user.
