Virtual 3D Sculpting

This paper presents a virtual sculpting method for interactive 3D object deformation. The method is based on the use of an electronic glove. A parametric control hand surface defined by an Open-Uniform B-Spline tensor product surface is first created to model the hand gesture. The geometric attributes of the object in the Euclidean 3D space are then mapped to the parametric domain of the control hand surface through a Ray-Projection method. By maintaining the distance between the mapped pairs, change of hand gesture can be efficiently transferred to control the deformation of the object.
