Simulation of Cloth with Low Stretch

Abstract

Cloth is a flexible thin material with low stretch. Although large stiffness can reduce stretch to some extent, it degrades numerical computing stability. Introducing effective constraints into the system is another common method to reduce stretch. In this paper, a novel constraint method is deduced and implemented. The bending deformation of cloth is firstly analyzed from micro-mesh view, based on which, constraint method is deduced. Then, constraint is combined with dynamic equation to simulate cloth. Overstretch of cloth is controlled at the same time realistic wrinkles and folds are maintained. Finally, based on this method, some experiments are conducted and the analysis and evaluation are given.
