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 ...
Preserving Realism in Real-Time Rendering of Bidirectional Texture Functions
(The Eurographics Association, 2003)
The Bidirectional Texture Function (BTF) is a suitable representation for the appearance of highly detailed surface structures under varying illumination and viewing conditions. Since real-time rendering of the full BTF ...
