BRDF-Shop: Creating Physically Correct Bidirectional Reflectance Distribution Functions
January/February 2006 (vol. 26 no. 1)
pp. 30-36
This articles presents an interface for quick and intuitive development of arbitrary, but physically correct, bidirectional reflectance distribution functions, or BRDFs. The interface, referred to as BRDF-Shop, gives artists the ability to create a BRDF through positioning and manipulating highlights on a spherical canvas. The authors develop a novel mapping between painted highlights and specular lobes of an extended Ward BRDF model. The implementation of BRDF Shop uses programmable graphics hardware to provide a real-time visualization of the material on a complex object in environment lighting.
