To guarantee color-correct simulations, it is therefore of great importance to perform appearance capture with a finer spectral sampling than the three broad band RGB channels. Capturing both shape and multispectral reflectance at a high quality is a challenging task and - to the best of our knowledge - has not yet been performed at the quality and speed of our approach. We acquire surface geometry and multi-spectral spatially varying reflectance of objects of up to a few centimeters height with the TAC7 device, which is available commercially as of lately. We demonstrate the improvements in color-accuracy and the overall quality of the appearance capture by relighting our accurately digitized objects under varying illumination conditions.10.2312/mam.2017132511-16
