In this paper, we propose an eecient t e c hnique for the animation of exible objects. Mass-spring model was employed to represent the exible objects. The easiest approach to animation with mass-spring model is explicit Euler method, but the explicit Euler method has serious disadvantage that it suuers fromìnstability problem'. The implicit integration(More)
