Virtual 3D sculpting

This paper presents a virtual sculpting method for interactive 3D object de formation. The method is based on the use of an electronic glove. A paramet ric control hand surface defined by an open-uniform B-spline tensor product surface is first created to model the hand gesture. The geometric attribut es of the object in the Euclidean 3D space are then mapped to the parametri c domain of the control hand surface through a ray projection method. By ma intaining the distances between the mapped pairs, change of hand gesture ca n be efficiently transferred to control the deformation of the object. Copy right (C) 2000 John Wiley & Sons, Ltd.
