A three-dimensional modeling system. The modeling system includes an antenna and a stylus. The stylus has at least one tag that communicates with the antenna to provide position signals of the tag, allowing the stylus to trace the surface of an object into a processor. The system may include more than one antenna, each producing an electromagnetic field within which the object to be modeled is positioned. The stylus may have two tags, which will allow derivation of orientation information from the position signals. The stylus may have a pressure-sensitive tip allowing the communication between the tag and the antenna to be controlled only when the stylus is in contact with the object to be modeled. The system may also have at least one tag attached to the object to provide more accurate information as to the position and orientation of the object relative to the points traced by the stylus. The stylus may also be used to trace an outline or other two-dimensional shape.
