ABSTRACT
Virtual environments containing humans moving and performing actions in real time are ubiquitous in computer graphics applications. Such characters are often clothed in woven fabrics. This paper presents a technique for visualizing woven clothes 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 representation obtained from the WIF with a procedural thread texture, a suitable cloth Bi-directional Reflectance Distribution Function (BRDF) and horizon maps. We employ the multi-texturing approach to meet the real time constraint. Thus our approach to visualizing woven clothes begins from weaving grammar specifications and converts them into textures that can be applied on clothes. We demonstrate the versatility of the proposed approach with examples.
