Realistic woven fabric rendering using deformed microfacet distribution function

We present a new procedural method for photorealistic rendering of woven fabric material. The goal of our research is to provide a new procedural method that renders photorealistic woven fabric without any measured data. The proposed method models the reflectance properties of woven fabric with alternating anisotropy and yarn-level surface normal manipulation. The proposed method models the reflectance properties of woven fabric with alternating anisotropy and deformed microfacet distribution function (MDF). The deformed MDF effectively represents the perturbed reflectance caused by bumps on the woven fabric surface. The experimental results show the proposed method can be successfully applied to photorealistic rendering of diverse woven fabric materials.
