Abstract: The work of great art performance in square has a great deal of dynamic visual effects scenes, which combines with formation variation, beautiful music, unique clothing and colorful light. According to the requirements of improving efficiency for scheduling section in handwork performance such as inefficient manual drawing, time-consumed and costly rehearsal, it is an effective way to use technology of computer simulation so as to implement real-time and dynamic intermediary platform among performer, director and audience. To meet various demands in practice, a vision-based formation generation was proposed that the path construction was studied based on linear fitting, pivot rotation and curve-following theory. The virtual crowd motion control method combined with the strategies of key frame, logic group management and pre-generated control path of virtual agents, which was applied in the design and rehearsal work and showed valuable significance.

Key words: great square art performance, virtual scheduling, path construction, motion control
