ABSTRACT
Rendering realistic fabrics is an active research area with many applications in computer graphics and other fields like textile design. Reproducing the appearance of cloth remains challenging due to the micro-structures found in textiles, and the complex light scattering patterns exhibited at such scales. Recent approaches have reached very realistic results, either by directly modeling the arrangement of the fibers [Schröder et al. 2011], or capturing the structure of small pieces of cloth using Computed Tomography scanners (CT) [Zhao et al. 2011]. However, there is still a need for predictive modeling of cloth appearance; existing methods either rely on manually-set parameter values, or use photographs of real pieces of cloth to guide appearance matching algorithms, often assuming certain simplifications such as considering circular or elliptical cross sections, or assuming an homogeneous volume density, that lead to very different appearances.

Real-time fiber-level cloth rendering
I3D '17: Proceedings of the 21st ACM SIGGRAPH Symposium on Interactive 3D Graphics and GamesModeling cloth with fiber-level geometry can produce highly realistic details. However, rendering fiber-level cloth models not only has a high memory cost but it also has a high computation cost even for offline rendering applications. In this paper we ...
Fast rendering of fabric micro-appearance models under directional and spherical gaussian lights
Rendering fabrics using micro-appearance models---fiber-level microgeometry coupled with a fiber scattering model---can take hours per frame. We present a fast, precomputation-based algorithm for rendering both single and multiple scattering in fabrics ...
Specular reflection from woven cloth
The appearance of a particular fabric is produced by variations in both large-scale reflectance and small-scale texture as the viewing and illumination angles change across the surface. This article presents a study of the reflectance and texture of ...
