Over the past 20 years, there have been many studies looking at how highlight disparity affects an observer's perception of glossiness. Most of these studies have used relatively smooth surfaces, and simple lighting models. We are using surfaces which are rougher and more naturalistic than those used before, using a rendering method which takes into account physically accurate properties of lig...

Color gamuts of acrylic paints generated by paint mixing and varnishing is introduced. A colorant data including unit k, unit s, and Saunderson coefficients, K1 and K2, are optimized. The simulation result of paint gamut rendering contradicts a belief of color mixing theory that yellow, blue, and red primaries produces any green. In addition, a statistic gloss model shows that varnishing makes ...
