The tradition of the Takigi O-Noh, or outdoor firelight Noh on the summer nights, dates back over a thousand years to performances associated with the religious ceremonies. In the Takigi O-Noh, Noh costumes of gold brocades shines and flickers beautifully with torches set around the Noh stage that provide the illumination. In this paper, we propose a real-time anisotropic BTF rendering method of Noh-costume under dynamic lighting with bonfire flickering effect, in the Takigi O-Noh lighting environment. First, we model the anisotropic reflectance of the Noh costume of gold brocades with the bidirectional texture function (BTF), which extended the Ashikhmin s bidirectional reflectance distribution function (BRDF) model. Then, we represent the bonfire flame by procedural texture as dynamic ambient map, which enable to perform the same calculation as direct calculation from environment map with filtered importance sampling.  a21867364 (ISSN)
