Lace curtain: rendering and animating woven cloth based on an impression-evaluation model

ABSTRACT

Woven fabric is frequently used in computer graphics. To express the realistic appearance of a woven fabric, it is important to represent its luster, transparency, and motion. In our previous study, we proposed a physically based BTDF model of woven cloth [Nomura et al. 2011] and a method of estimating the motion properties of woven cloth from subjective impression [Ishida et al. 2012]. However, for the further enhancement of the texture of materials in animations, it is necessary to construct a comprehensive impression model for the evaluation of woven cloth that includes the relationship between optics and motions, impressions and emotions that are evoked by the impressions. In this study, we propose an impression-evaluation model for the rendering of woven fabrics.
