Simple, Robust, Constant-Time Bounds on Surface Geodesic Distances using Point Landmarks
(The Eurographics Association, 2015)
In this paper we exploit redundant information in geodesic distance fields for a quick approximation of all-pair distances. Starting with geodesic distance fields of equally distributed landmarks we analyze the lower and ...
Extrapolating Large-Scale Material BTFs under Cross-Device Constraints
(The Eurographics Association, 2015)
In this paper, we address the problem of acquiring bidirectional texture functions (BTFs) of large-scale material samples. Our approach fuses gonioreflectometric measurements of small samples with few constraint images ...
