Abstract
The reflectance of fabric surface is commonly represented by a bidirectional reflectance distribution function (BRDF). To generate the image-based BRDF from measured data, it requires an enormous amount of measurements. In this paper, we propose an efficient image-based method for rendering the anisotropic BRDF of silk-like woven fabrics based on the micro facet surface geometry determined by the cross-sectional shape of fibers, twist of yarns, and type of weave. We develop an image-based method for generating the BRDF of silk-like woven fabrics from measurement of the reflectances caused by the incident light only in the direction perpendicular to the fabric's surface.
