Abstract :
This article presents a method to model flexible linear bodies: ropes, cords, springs, and the like, for animation production. The resulting models can easily be animated in a manner that convincingly fakes dynamic behavior. The models were animated using the keyframe animation system, which provides traditional spline-based control of the models´ animatable parameters
