Abstract
SummaryTo make a more thorough understanding of human movement, the research of virtual human running based on the CCD (Cyclic‐Coordinate Descent) algorithm was focused on. First of all, the CCD algorithm, the rotation range of the human joint, the running cycle, the key moment of running movement, and the decomposition of running movement were introduced in detail. Then, the inverse kinematics based on the CCD algorithm was solved, the inverse kinematics in the running was solved, and the motion simulation of the upper body and the specified path were carried out. Finally, the simulation results were analyzed. The results showed that the parameters such as the percentage of the support period, the vacant height, the running level, the step frequency, and the frame rate were adjusted by the interactive mode. In a word, it makes the running posture generated diversified and more characteristic.
