Surface deformation using the sensor glove

Intuitive 3D surface control and deformation are crucial to CAD/CAM. To do this in a virtual environment, however, the technique must be very efficient. A common method for shape deformation is the free-form deformation (FFD) method, in which the complete object is deformed by deforming a 3D grid of the object. In this paper, we propose an intuitive method for surface deformation based on deforming a hand surface, which is basically a bicubic B-spline surface interpolating or approximating key data points of a sensor glove (i.e. finger joints and palm center of the user’s hand). By setting up a corresponding mapping between the virtual object being deformed and the hand surface, the object can be deformed with the control of the sensor glove. As the user flexes his/her fingers, the object changes its shape accordingly. Such control can be local or global. For local deformation, we introduce a region filter function which imposes locality on the mapping/deformation. The new algorithm...
