THE END OF FLAT SCREENS?

The mantra 3D and 3G are often heard these days!! Of these 3-D monitors are emerging successfully in various standards..Perspecta 1.9 is the first 3D display that lets users view 3D moving images from any direction around it. It can be viewed from top or from below. The viewer can also zoom in and out in real time. The system includes a 20-inch(50.8cm) dome displaying full-colour and moving images that occupy a volume in space,giving users a 360 degrees all encompassing view—without the need for special 3D goggles. Perspecta is plug-and-play , rendering all movement from widely used open-standard 3D applications.

Developed by US-based Actuality Systems, the Perspecta System is made up of a circular white polymer screen, 25cm in diameter, mounted on a 1-metre-high black box so that people can walk around it. Like a giant spinning lollipop, the screen, encased in a transparent polycarbonate shell, turns at 15 revolutions per second.

To display the image, software inside the Perspecta chops a 3D model generated by the computer into 198 separate pieces, like slices of cake, which are then projected onto the screen in quick succession by a graphics accelerator that feeds image slices to an optical system mounted below the screen. The result appears to the viewer like a 3D image composed of 100 million “volume pixels” or “voxels”.
