Polynomial Wavelet Tree is a new tool for accurate and efficient compression of BTFs. The key idea is to separate directional and spatial variations by projecting the spatial BTF domain (i.e., the light-dependent textures) onto a wavelet basis and to approximate these light-dependent wavelet coefficients with a polynomial function. Fitting wavelet coefficients instead of data themselves is a more efficient approximation compared to previous solutions since low frequency light transitions are smooth and higher frequency coefficients can be quantized with less importance. This wavelet projection and the light-dependent polynomial approximation is done for each view-point. Our solution is also designed for efficient high quality materials rendering on GPU.Read less <
