Abstract: This article proposed a description model of athletic posture for sinitic opera, which contained body structure, spatial orientation and movement force effect three dimensions. A multi rigid model is established based on the relationship between nodes and edges, record the movements of each part with geometric figures to establish the skeleton hierarchy of multiple joint points. In addition, we applied the description method on the virtual human in digital sinitic opera performance system, which is designed based on virtual reality (VR) technique. Also, we extracted the complete set of human motion from sinitic opera such as martial action and choreographic performance in Mei Lanfang faction repertoire, and design the virtual human movements by combining the posture base on the kinematics model above. The results show that this method can effectively realize the digital performance design of sinitic opera and enhance the audience's experience in virtual interactive environment.
