A simple Mass-Spring system for Character Animation

Mass-Spring systems are used widely to implement animation of deformable objects. We have developed a simple mass-spring system to animate a character based on physics. The reason we adopt a mass-spring system is simply we wanted more realism than Free Form Deformation (FFD) techniques can offer, as modeling physical processes. Also, this technique is preferred over Finite Element Methods (FEM) because these methods are computationally expensive and not always is possible to develop real time applications using them. Instead, MassSpring systems offer physically based behavior together with interactive and, sometimes, real time simulations. In addition, our implementation of the physic model can be used for a more general application, not only animation.
