The need for rendering woven fabrics arises frequently in computer graphics. Woven fabrics have a specific appearance, luster, and transparency. We have proposed a BTDF model using the Henyey-Greenstein Function (HGF)[Uno et al. 2008]. However, since the HGF is a phenomenologically based model, to make the model more accurate, a physically based model is introduced. This paper proposes a new microfacet BTDF model for woven fabrics. we embed a multi-band structure with a fluorescent property into the model, and the results of the rendering show the powerful influence of fluorescence on the appearance of the visible band.
