Tecate is a virtual-reality WWW markup language for 3D viewing
of scientific data, from the Project Sequoia 2000 group at the
San Diego Supercomputer Center. 3D data objects (e.g., in GIS
or informational "landscapes") act as "hot links" to additional
information, which can be viewed with 3D visualization techniques.
Ann Redelfs The month-old "virtual museum" 3D modeling technology used in
the "Star Trek: The Next Generation" CD ROM has found a surprising
use. Apple's Quicktime VR will be used to help TV viewers retrace
the killer's path for the O.J. Simpson trial. 400 photographs
were used to build 3D models of 26 sites, permitting the same
kind of roaming and zooming as if live cameras were present.

The archive of 3D objects, models, and related materials
at anonymous FTP site avalon.chinalake.navy.mil is moving
to avalon.vislab.navy.mil. [Francisco X. DeJesus
A new stereo display system creates a 3-D effect from single-
camera motion pictures. The image is offset right and left as
it's presented alternately to your two eyes. The result appears
flat, of course, until something moves. Then your brain picks up
the segmentation cues and begins to perceive the scene in 3-D.
[Suzanne Oliver, Forbes, 1/16/95, p. 94.] (It's not true depth,
of course, but endoscopic surgeons find it very helpful.)
From the Computer Vision Home Page you can reach over
8,000 documents in just four link traversals -- all listed in
a searchable index. Over 80 research groups are referenced
directly. For visual edge detection, 10,000 instructions per second
(e.g., from a 100 MIPS workstation) produce the coarse functional
equivalent of 100 neurons in the optic nerve. Such a workstation
might fully simulate an ant if we understood all the biological
hacks and open-loop shortcuts. But note that insects seldom
behave wisely and most die before reproducing. Human-level
performance with $10K workstations may take us until 2030.
"We can hack our way incrementally to human-level intelligence,
because stupid old Darwinian evolution works that way, and it
got there. And from time to time we can cheat, and copy an
answer. That's why our robots had cameras even before they knew
what to do with them. Nature had shown us that eyes were a good
idea." [Hans Moravec ([email protected]), comp.ai, 11/17/94. Chuck

The Fox 2000 "electronic nose" from AlphaMOS (France) uses
gas sensors made of surface acoustic-wave devices, conducting
polymers, and metal-oxide silicon to recognize odors in 10-30
seconds. Neural Computer Sciences (Southampton) will be studying
neural networks for faster recognition. [Computer News, 12/7/94.]
