| 内容記述 | Full-dimensional (8-D) BSSRDF completely expresses the various light interactions on object surface such as reflection and subsurface scattering. However, it is difficult to sample full-dimensional BSSRDF because it requires a lot of illuminations and observations from every direction. There are many researches which approximated BSSRDF as a low-dimensional function by only considering the medium as homogeneous or assuming isotropic scattering. Therefore, in this paper, we show a novel sampling and analyzing method for full-dimensional BSSRDF in real scenes. We sample this full-dimensional BSSRDF using a polyhedral mirror system to place a lot of virtual cameras and projectors. In addition, we propose a method of decomposition of BSSRDF into isotropic and anisotropic components for scattering analysis. We show the empirical characteristics of subsurface scattering inside a real medium by analyzing sampled full-dimensional BSSRDF. | |||||||
