Manipulation of dynamically deformable object

An approach to realize manipulation of elastic object in virtual environment is discussed. In the approach, the behavior of elastic object during interaction is separately described by two components: rigid-body motion and elastic deformation. The component of motion is simulated by solving equations of motion, while the component of deformation is reproduced from a set of deformation sequences in response to impulse force, or impulse response deformation model. A prototype algorithm and interface environment was built and experiments to evaluate the approach were carried out.
