Abstract
A method for developing computer animation using dynamics analysis comprises analyzing the basic motions of a moving body such as a human or animal body and inputting the force or torque exerted on each joint into a database, dividing each body segment from other body segments and calculating the movements of the segments by applying dynamic equations, checking constraints including the articulation of the moving body and the range of movements of the joint, calculating motions and forces produced by the restraints by applying the inverse dynamics, calculating the movements of individual segments by applying dynamic equations to develop new motions, checking restraints including the articulation of the moving body and the range of movements of each joint, calculating the motions and forces due to the restraints by inverse dynamics, and displaying the motions and forces.
