However, designing realis tic shading models and capturing real fabric samples are both challenging tasks. Previous work ranges from applying generic shading models not meant for fabrics, to data-driven approaches scanning fabrics requiring expensi ve setups and large data. None of these approaches can turn a single woven fabric sample photograph into a high-accuracy reconstruction enabling co mpact storage and efficient rendering.\nIn this paper, we propose a woven fabric material model and a parameter estimation approach for it. Our ligh tweight forward shading model treats yarns as bent and twisted cylinders, shading these using a microflake-based BRDF model. We propose a simple fab ric capture configuration, wrapping the fabric sample on a cylinder of kno wn radius and capturing a single image under known camera and light positi ons. Our inverse rendering pipeline consists of a neural network to estima te initial fabric parameters and an optimization based on differentiable r endering to refine the results. Our fabric parameter estimation achieves h igh-quality recovery of measured woven fabric samples, which can be used f or efficient rendering and further edited.\n\nRegistration Category: FULL ACCESS, EXPERIENCE PLUS ACCESS, EXPERIENCE ACCESS, TRADE EXHIBITOR\n\nLang uage: ENGLISH\n\nFormat: IN-PERSON URL:https://sa2022.siggraph.org/en/full-program/?id=papers_207&sess=sess15 3 END:VEVENT END:VCALENDAR
