| Abstract in different language: | A new method for the evaluation of the bidirectional reflectance distribution function (BRDF) is presented. The proposed procedure foregoes the usage of special equipment like pohotogoniometers or imaging reflectometers but rather uses of-the-shelf hardware like CCD cameras. The BRDF is determined from the image data, thus capturing several incident angles at each measurement. Using a diffuse reflectance standard the effects of ambient and stray light can be reduced. The presented method offers an easy and cost efficient way to measure material properties needed for physically based rendering algorithms. |
