Abstract
There is provided a method and a device, each of which can improve the reproducibility of the appearance of an actual product. A design layer data creation deviceincludes: a measuring instrumentwhich measures a BRDF of a design layerconfigured by a paint color layerand a clear coat layer; and a calculation elementwhich creates design layer data on the basis of an approximate BRDF according to a BRDF model. The calculation elementdefines the approximate BRDF by respectively obtaining coupling coefficients Ks, Ks, and Kd of a specular reflectance distribution function and a diffuse reflectance distribution function so as to approximate measured BRDF data.
