cover story

18 In virtual fashion
BY STEPHEN CRAY
Computer graphics and virtual reality are being combined to enable
clothes-shoppers to serve as their own clothes models for garments that are
digitally fitted and converted into unique 2-D patterns. Everything off the
rack in effect becomes custom tailoring, choice of fabric and all.

26 Firewalls fend off invasions from the Net
BY STEVEN W. LODIN & CHRISTOPH L. SCHUBA

inexpensively using IC processing techniques, they can be diced in planar
or linear arrays, as in the wavelength-division multiplexer shown.
