Abstract :
An improved discrete mass-spring model is proposed for modeling of deformation of soft object. And the algorithm to realize real-time force reflection to the human operator based on this model is given with suitable parameters. Finally, the experiment demonstrates that this novel physics based deformation model has the properties of high accuracy and quick computational speed by comparison with other deformation models.
