Popular Science reports via DARPA:
Long gone are the days of pushing plastic armies around hand-drawn maps. Today’s military planners deserve technology of the future, and that means nothing less than 3-D holograms will do. Luckily, we have DARPA, ever-ready to step in with a solution. The Urban Photonic Sandtable Display (UPSD) allows up to 20 participants to simultaneously view and manipulate the 360-degree, 3-D image on the table, without having to wear 3-D glasses.
The display can be expanded to as large as six feet, and has a visual depth of up to 12 inches. UPSD is also interactive – battle planners can freeze, rotate and zoom in on the images. They can also print out two-dimensional representations of the 3-D data (seen above) that troops can carry with them on their missions.
Zebra Imaging won the contract to create the technology for UPSD, and DARPA is using LIDAR (Light Detection and Ranging) systems for the data.


Following the 3D trend, George Lucas has found yet another way to make money from the Star Wars saga.
It seems that every big blockbuster to hit box offices lately have been in 3-D. From Avatar to Alice In Wonderland, and currently Despicable Me, 3-D is used as common as computer animation. Now television companies are working on bringing the life-like effects into your home.
