Estimating reflectance functions using a cyberware 3030 scanner

Abstract

Measuring reflectance properties is important to the fields of computer graphics and vision. We present a novel, rapid measurement technique specifically targeting the reflectance properties of skin. Using a Cyberware laser scanner to capture range and radiance data, a sampling of the surface radiance function under a broad range of incident and view directions is constructed. This function is at the core of local reflectance computation and the recovered data can be used for various tasks including rendering, guiding models, albedo estimation and more. We qualitatively analyse the resulting data, and illustrate a number of possible uses for it. © Springer-Verlag Berlin Heidelberg 2007.
