Abstract
This paper presents the design of an extensible animation system in which rigid and deformable multibody systems are animated from their geometric models and the specification of kinematic and dynamic constraints. Theoretical, numerical and practical aspects of the system implementation are presented. One of its main features is the automatic derivation of the symbolic form of the motion equations from a physical model created interactively. This process is detailed by means of a simple example. Besides achieving motion control by the application of direct dynamics, the system provides animation of deformable objects, automatic motion control from a specified motion without having to determine the forces required to produce this desired effect, and object collision detection and response. Experimental results are presented to illustrate each type of animation control. Finally, the applicability of our animation system to scientific simulation is discussed.
