The need for rendering woven fabrics arises frequently in computer graphics[N Adabala, N Magnenat-Thalmann, G Fei 2003]. Woven fabrics have a specific appearance, luster, and transparency. We have proposed a BRDF/BTDF model using the Henyey-Greenstein function and an algorithm for the real-time rendering of woven fabrics based on the texture look-up table[Uno et al. 2008]. However, in order to make the model more accurate, the microlevel BRDF/BTDF is necessary. The objective of this study is to express a more detailed texture of the cloth by creating a 3D model that especially takes into consideration the "twisted structure" of the yarn in the fine woven structure of the cloth and by making the rendering algorithm more precise.
