A Rendering Method for Woven Clothes Reflections
نویسندگان
چکیده
We proposed a physics-based rendering method for reflection of woven textiles. Both reflection properties of fibers and yarns are taken into account, which are the primary factors affecting visual appearance of cloths. The reflection from fiber surfaces is analyzed using Kirchhoff diffraction theory, assuming a statistical surface. Yarns are usually consisted of a group of fibers and they are simulated by a group of parallel infinite long triangle prisms which considers the different cross section shapes of fibers. The reflections from yarns are derived according to such geometry, taking into account of masking and shadowing. The model is compared with experimental data from spectrophotometer measurement on different woven textile samples and fit very well by numerical simulations. Theoretically the model is suitable to different kinds of woven textile structure and fiber materials. Also it can be developed to be used in computer graphics applications.

Real-time Visualization of Woven Textiles
This paper presents a technique for visualizing woven textiles in real time, while optimizing the realistic appearance. The proposed approach supports rendering of complex weave patterns by adopting Weaving Information File (WIF), a standard from textile Computer Aided Design (CAD) for representing the grammar of weaving. We develop a realistic rendering scheme by combining the grammar represen...
متن کاملAn Evaluation on Woven Cloth Rendering Techniques
Advances in graphics hardware have led to large number of new technologies for cloth rendering. However, it is not clear what technology is suitable for what types of applications. While computer games need compact representation and high efficiency in cloth rendering techniques, fashion related applications often need high flexibility for rendering different fabrics. So far no research exists ...
متن کاملProcedural Approach for RealisticWoven Fabric Rendering
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 experimental results show the ...

Noh is a Japanese historical play lasted for 600 years and Noh costumes are precious cultural heritage and are made of specially woven silk fabrics. The reflectance of such fabric surface is commonly represented by a large-scale of bidirectional texture function (BTF) from measured data by a gonioreflectometer with 2 degrees of freedom of the light source and 2 degrees of freedom of the observi...
متن کاملReduction of skin bacteria in theatre air with comfortable, non-woven disposable clothing for operating-theatre staff.
Conventional loose-weave cotton operating garments were compared with clothing of a non-woven fabric to test their efficacy in reducing the dispersal of skin bacteria into theatre air. When men wore operating suits made of the non-woven fabric dispersal of skin bacteria was reduced by 72%. When all the operating-theatre staff wore suits and dresses of this fabric air bacterial counts during ope...
