We integrate the rendering of measured BRDF data in the Advanced Rendering Toolkit (ART), which is developed since 1996 from the Institute of Computer Graphics and Algorithms of the Vienna University of Technology. Also we evaluate the generated images, with polar plots, to show their reflectance property. Also we show our trilinear interpolation approach, which was used for the data from the Cornell University. To present our work we also rendered several images with the ART pathtracer.

               method to generate reference images for analytical models.
               But before we can render measured data it has to be acquired
               and then fitted and interpolated. In this thesis we review
               two BRDF (Bidirectional Reflectance Distribution Function)
               databases from different Universities. One database consists
               of Spectral data where the other only measured the materials
               in RGB color space. Furthermore we introduce the reader in
               the basic BRDF models and in the basics of Monte Carlo
               sampling methods.   We integrate the rendering of measured
               BRDF data in the Advanced Rendering Toolkit (ART), which is
               developed since 1996 from the Institute of Computer 
               Graphics and Algorithms of the Vienna University of
               Technology. Also we evaluate the generated images, with
               polar plots, to show their reflectance property. Also we
