A Data-Driven Approach for Real-Time Clothes Simulation

A data-driven approach for real-time processing of clothes, particularly suitable for simulating dresses worn by virtual characters, is proposed.It starts, prior to real-time simulation, by analyzing cloth behavior in relation to the underlying skeleton movement from a pre-simulated sequence of the cloth obtained using any high quality off-line simulators.The idea is to use this analysis to find an optimal combination of physics-based simulation and geometric approximation of the simulator; potentially colliding regions are defined on the cloth such that they will hold true for the skeleton movement that closely matches that of pre-simulated sequence.At runtime, using these analyses, our simulation process provides both visually pleasing results and performance, as long as the motion of the character remains sufficiently close to the original sequence used for the pre-computation.
