Toward Estimation of Yarn-Level Cloth Simulation Models

Efﬁcient and realistic cloth simulation is an unsolved problem, with yarn-level models emerging as a new alternative thanks to new hardware capabilities. Modeling yarns as ﬂexible rods with persistent contacts enables a very robust and efﬁcient simulation. However, this assumption also complicates the deﬁnition of elastic deformation potentials. This work explores more accurate yarn-level cloth models together with experiments that compare model features in order to detect shortcomings in the persistent contact model. In particular, we have implemented a discrete elastic model of ﬂexible yarns with contact which treats yarns as unidimensional splines, together with a model that discretizes yarns using three-dimensional ﬁnite elements.
