The photometric sampling method [4] extracts shape and reflectance properties of surfaces (Lambertian,specular,and hybrid)by using multipleillunrinationdirectionsand asingle viewi...
This article proposes a local photometric model that compensates for specular highlights and lighting variations due to position and intensity changes. We define clearly on which ...
Line-art illustrations are effective tools for conveying shapes and shading of complex objects. We present a set of new algorithms to render line-art illustrations of dynamic and s...
