Measurement and Analysis of Reflection Properties of Art Paints
This paper deals with measurement and analysis of the 3D reflection properties of painting materials such as oil paints and water paints. First, we measure light reflected from a variety of painting surfaces by using a goniophotometer and acquire the surface reflectance data at different incident and viewing geometries. Next, the surface reflection is described by a mathematical model using the Torrance-Sparrow model. An algorithm is presented for determining the model parameters, including spectral reflectance, specular intensity, surface roughness, and refraction index, from the observed reflectance data. Some difference in reflection properties is suggested between oil paints and water paints. Finally, images of objects with the two paints are rendered.
