Abstract

This paper deals with a method to effectively compress the measured reflectance data of pearlescent paints. In order to simulate the coated surface realistically, it is requested to measure the reflectance of the pearlescent paints by using multiple wavelengths. The wavelength-based reflectance data requests a large amount of storage. However, we can reduce the size of the measured BRDF and retain the accuracy the data by using several factorization algorithms. In this paper, we analyze the decomposition of the measured BRDF of pearlescent paint and find the number of lobes or basis functions to retain the visual accuracy of the measured reflectance.
