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 device 100 includes: a measuring instrument 151 which measures a BRDF of a design layer 210 configured by a paint color layer 202 and a clear coat layer 201; and a calculation element 120 which creates design layer data on the basis of an approximate BRDF according to a BRDF model. The calculation element 120 defines the approximate BRDF by respectively obtaining coupling coefficients Ks1, Ks2, and Kd of a specular reflectance distribution function and a diffuse reflectance distribution function so as to approximate measured BRDF data.
