Simulation of virtual human running based on inverse kinematics

Virtual human is more and more used for different application in multimedia learning environment, and his motion impact the immersion directly. In this paper, running motion control technique of virtual human is researched. According to the idea of motional superposition, the running cycle is divided into six stages. The six stages are modeled respectively. In this method, the keyframes of running motion are created. In the process of solving keyframes, CCD (Cyclic-Coordinate Descent) algorithm is used to solve the inverse kinematics problems. The tweenframes are produced by interpolating between these keyframes to make movement coherent. Moreover, introduce motion characteristic parameters to make the postures of running diversely.
