SUMMARY:Woven Fabric Capture from a Single Photo
DESCRIPTION:Technical Communications, Technical Papers\n\nWoven Fabric Cap
ture from a Single Photo\n\nJin, Wang, Hasan, Guo, Marschner...\n\nDigital
ly reproducing the appearance of woven fabrics is important in many applic
ations of realistic rendering, from interior scenes to virtual characters.
However, designing realistic shading models and capturing real fabric sam
ples are both challenging tasks. Previous work ranges from applying generi
c shading models not meant for fabrics, to data-driven approaches scanning
fabrics requiring expensive setups and large data. None of these approach
es can turn a single woven fabric sample photograph into a high-accuracy
reconstruction enabling compact storage and efficient rendering.\nIn this
paper, we propose a woven fabric material model and a parameter estimation
approach for it. Our lightweight forward shading model treats yarns as be
nt and twisted cylinders, shading these using a microflake-based BRDF mode
l. We propose a simple fabric capture configuration, wrapping the fabric s
ample on a cylinder of known radius and capturing a single image under kno
wn camera and light positions. Our inverse rendering pipeline consists of
a neural network to estimate initial fabric parameters and an optimization
based on differentiable rendering to refine the results. Our fabric param
eter estimation achieves high-quality recovery of measured woven fabric sa
mples, which can be used for efficient rendering and further edited.\n\nRe
