  abstract = {Efficient physically accurate modeling and rendering of woven cloth at a yarn level is an inherently
              complicated task due to the underlying geometrical and optical complexity. In this paper, a novel
              and general approach to physically accurate cloth rendering is presented. By using a statistical
              volumetric model approximating the distribution of yarn fibers, a prohibitively costly explicit
              geometrical representation is avoided. As a result, accurate rendering of even large pieces of
              fabrics containing orders of magnitudes more fibers becomes practical without sacrifying much
              generality compared to fiber-based techniques. By employing the concept of local visibility and
              introducing the effective fiber density, limitations of existing volumetric approaches regarding
              self-shadowing and fiber density estimation are greatly reduced.}
