Abstract
A sculpturing input device for computerized 3D sculpturing includes a base for connection to a computer loaded with a virtual engraving program, and a magnetic stylus for use with the base for controlling a virtual engraving tool to cut a virtual object of the program. An optical position measuring system is provided in the base for measuring the position and direction of the stylus relative to the base, and determining the position and direction of the tool relative to the object. A magnetic force feedback system is provided in the base for exerting a magnetic resistive force upon the stylus when the tool cuts into the object, thereby simulating a counteracting resistive force of the object being cut.
