MERL BRDF reconstruction using PDV basis measurements

This supplementary provides visual comparisons of all MERL BRDFs and its reconstruction. We virtually simulated the basis measurements from MERL BRDF data. The left figures of each row are the rendered results of reference BRDFs. The middle figures show its reconstructed BRDF. The right figures illustrate the luminance differences of each BRDF. All the reconstructed BRDFs were recovered by using basis vector measurements. The dp basis measurement was done at a fixed θr = 70 degrees. The luminance differences are coded by jet colormap from MATLAB as below.

The summary plots of PSNR is shown here.
