Our 2011 paper entitled “A hybrid iterative solver for robustly capturing Coulomb friction in hair dynamics” has been awarded a Test of Time Award at Siggraph Asia 2023 in Sydney.
This paper introduced the first nonsmooth algorithm able to capture dry friction in flexible fibre assemblies in a fast and robust manner. The method was inspired by the French Moreau school on nonsmooth mechanics pioneered in the 80’s, which was essentially applied to granular materials and rigid bodies at that time. The frictional contact algorithm was implemented in the free so-bogus library and was used in several FX movies (including The Hobbit: An unexpected journey and Superman: Man of steel) for simulating hair and fur realistically.
