Abstract
Biomechanical modeling and simulation of the human body is a fundamental technology in many fields such as graphics, robotics, and medical and sport sciences. This talk presents our effort towards building realistic human body and motion models and developing associated computational algorithms. The key issue in handling real human body is how to balance between the required precision/reality and available computational resources. Appropriate level of approximation and efficient algorithms should therefore be chosen based on the application, although this is not straightforward due to the complexity of the system. We have developed a number of modeling methodologies and computational algorithms for dynamics simulation, motion analysis, and motion synthesis for various applications including character animation, robot control, and biomechanical analysis. In this talk, we describe some of our main results, including (1) parallel forward dynamics simulation of articulated rigid bodies, (2) flexible inverse kinematics for character animation, (3) motion synthesis from human motion capture database, and (4) detailed biomechanical modeling of the human body.
