Abstract
In order to create photorealistic images, we need to know how light is reflected from differ-ent
materials. The bidirectional reflectance distribution functions (BRDF) plays an important role in
modeling the reflectance of materials. This paper presents a framework for extracting BRDF samples
from multiple photographs, which are taken from the same viewpoint but under different lighting di-rections,
of an arbitrary object. After collecting samples, we use a smoothing interpolation to ap-proximate
the complete BRDF from the measured samples.
