Holograms - The Future Without The Funny Glasses

hopbine writes "MIT Technology Review has an interesting article on the latest trends in holograms. I like the NYU's NY3D system. It puts an LCD display in front of a normal CRT and by monitoring the viewers eye movement it can flash on and off parts of the LCD screen showing each eye a different image through the gaps, producing a 3D image. Another research project shows how researchers can "feel" the hologram. Maybe the holodeck is not that far away !"

Target Marketing

Did anyone else check out the 3D Volumetric Display at Actuality Systems? Very, very cool stuff.

Their marketing department also seems to realize the average consumer will use this for 3D pr0n, as their Photographs page takes special care to include a "last but not least" shot of "[The] pelvic region of female anatomy."

w00t! :-)

Duplicate article, duplicate discussion

A few points:

• This article was already posted on Slashdot just two weeks ago.
  
• Both times, the story poster focused on the stereoscopic display being developed at NYU instead of the much more ambitious (and much cooler, IMHO) holographic display being developed at MIT.
  
• Just because something looks 3D doesn't mean it's a hologram, i.e. the stereoscopic display is not a holographic display.
  
• Each system has its advantages and disadvantages. The stereoscopic display has the advantage of requiring less computation and viewer selectivity. It has the disadvantage of the complication of viewer tracking, and it requires that a separate image be rendered for each viewer. The holographic display has the advantage of being a true three-dimensional image--you can move your head to see the object at different angles without re-rendering, and a single rendered image can be viewed by multiple viewers. The disadvantage is that rendering a holographic is very computation-intensive, and most of the information rendered in a holographic image is not seen by the viewer.
