I've seen a device in use at UCSD's Visualization Laboritories (at the
San Diego Supercomputer Center, 619/534-5055).  A tiny hand-held
device, I believe, transmits some kind of signal that is triangulated
on by a sete of receivers.  S'all I know... maybe UCSD/SDSC's viz lab
can answer questions in detail.  Ask for the Visualization Lab, and ask
for one of the Silicon Graphics gurus.

The device is used to digitize three-dimensional objects, such as
human facial features, skeletons, etc.
