Abstract: This paper introduces a method based on honeycomb structure and four gates principle to synthesize interactive animation scenes of multi-characters,where the number of opponents is unknown nor the types of actions.Our method uses theory from complex network area to synthesize crowd animation.Random graphs and a honeycomb structure-based uniform network are used to synthesize animations of multi-characters.In order to create interactive scenes,a three-dimension human motion reconstruction method with two-layer is implemented,which separates the motion reconstruction from the motion recognition.Experimental results show that our method is capable of synthesizing realistic interactive animations of multi-characters.
