Polhemus Navigation Sciences makes the 3-Space 3-D digitizer system for 3-D digitizing (They also make the Isotrak for things likes tracking head movements for heads-up displays and other products like the DataGlove (See Oct. Sci-American cover)) Anyway it uses 3 orthognal magnetic coils and a small receiving device that measures distance and orientation of the device. It measures position and orientation (6 Degree of freedom) on all three axes.
