Method and apparatus for generating and interfacing with rigid and deformable surfaces in a haptic virtual reality environment |
摘要 |
A method for haptically deforming a virtual surface within a haptic virtual environment is used to plastically deform the virtual surface of a virtual object by sensing a user's position in real space, determining a haptic interface location in the haptic environment based thereon, and determining whether the virtual surface collides with the haptic interface location. Upon detection of a collision above a threshold force, a visual representation of the virtual surface is plastically deformed and a corresponding force is calculated and fed back to the user. The virtual surface can be visco-elastically deformed. |
