Abstract: Realistic effective clothing animation simulation involves many factors, including the lifelike animation rendering, stable animation modeling, interaction control of the adjustable parameter and so on. An interactive clothing animation method based on physics is studied. According to the content feature of model and animation resources, we design an effective way of storage and provide the interface to adjust the parameters interactively. We build implicit constraint dynamics system, accelerated collision detection and the constrained optimization calculation model, and calculate clothing animation. The simulation based on Unity 3D engine is rendered to present garment animation simulation effect under different virtual light. Experiment results show that our virtual clothing animation platform has superior interactivity, stability and visual fidelity.

Key words: clothing animation, interactive, clothing dynamics, collision detection, collision response
