BRDF Measurement and Representation Framework

BRDF 측정 및 표현을 위한 프레임워크

In this paper, we present a simple framework to measure BRDF(Bidirectional Reflectance Distribution Function) values of objects and to render them using the values more realistically. There are lots of BRDF measurement methods, but the methods have been separated from the effective rendering of the values. Therefore, we suggest the framework which includes the BRDF measurement methods of objects and the effective rendering methods of the measured BRDF data. Before measuring the BRDFs, we do light sources analysis, camera calibration and display device characterization. After measuring them, we apply them to the characterized display device for rendering effectively and realistically.
