Abstract: This paper proposes a path-driven character animation synthesis method which can be used to synthesize various natural large-scale human movements.By the method,firstly,the path to be matched is divided into a series of short curve segments.Then each short curve segment is associated with a mostly matched motion clip stored in a structural Motion State Machine.These motion clips are then connected one by one to form the final continuous human motion data,in meeting the motion path constraint.Besides,the method also allows user to interactively associate specific motion clip to any curve segments.The proposed method is particalarly suitable for such occasions that the path to be matched is in large scale,or multiple paths are matched simultaneously,or paths intersect frequently.
