Abstract
We propose a real-time bidirectional texture function (BTF) and image-based lighting (IBL) rendering of the Takigi Noh based on reflectance analysis. Firstly, we measured a sample of the Noh costume by omnidirectional anisotropic reflectance measurement system called Optical Gyro Measuring Machine (OGM), and we modeled the BTF of the Noh costume based on multi-illuminated High Dynamic Range (HDR) image analysis and modeled Noh stage in 3D based on archival records. Secondly, we captured motion data of Noh player, and modeled Noh player wearing a costume. To achieve the real-time rendering, we modeled the Noh costume by mass spring damper model. Finally, we modeled animated ambient map based on the Improving Noise to achieve the real-time dynamic lighting by fire of the Takigi, and we calculated the optical reflection by the IBL and deformation of the Noh costume.
