Interactive Deformation of Hybrid VR Models
(H. Sun)

The conventional representation of objects in virtual environments has been limited to solid, robust geometrical objects. Later, the deformable objects such as cloth, rubber balls, plants, skin, or rope can be displayed more naturally with the calculation of suitable distortion and deformation. This project will develop effective simulation techniques, such as constraint methods and adaptive local deformation in interactive physics-based modeling. It will examine what and how these methods and laws are incorporated to simulations in virtual environment to make the objects more realistic. The trade-off between faster display rate and accuracy (the object's shape, distortion) in the contact area of interactive object will be experimented by examples. Hybrid VR models (surfaces/volumes) will be incorporated in an uniformed testing framework. With the deformable objects, the user interactivity can be greatly enhanced in virtual-reality simulations.
