Polynomial wavelet trees for bidirectional texture functions

Abstract

Bidirectional Texture Functions (BTF) currently offer the highest quality representation for the appearance of complex real-world materials (see Figure 1). However, BTF acquisition leads to a huge amount of data and thus cannot be used as is. In a pixelwise approximation, working with light varying material for each eye direction is more convenient since… (More)
