Ahmedabad, 16 November 2012
So which is the technology that would create virtual presence of Gujarat Chief Minister Narendra Modi possible in four rallies simultaneously this Sunday?
Well, it’s called 3D holographic projection technology.
This technology first received attention worldwide in 2008 when Prince Charles addressed the World future energy summit and made his first appearance as a hologram in a bid to reduce the royal carbon footprint. A video of the event has been presented above. A six-minute address of Prince Charles was recorded in the drawing room of his Clarence house earlier.
In past, American leader Al Gore launched Live Earth Tokyo in a high-tech, virtual way – as a hologram using Holographic Projection.
This technology has been used widely to launch the products and create fun.
As per the details available online on this technology, the images used are three-dimensional images, but projected as two-dimensional images (2D/3D) into a 3D stage set, therefore the mind of the audience create the 3D illusion. This means that production costs are minimal, needing only the single camera lens for filming and a single projector for the playback – hence the phrase ‘Glasses-free viewing’.
The primary components of projecting the subject are; A video projector, preferably DLP with an HD card/minimum native resolution of 1280 x 1024 and brightness of 5000+ lumens, for smaller cabinet installations, a high quality TFT Plasma or LCD screen, a hard-disc player with 1920 x 1080i HD graphics card, Apple or PC video server, DVD player, a specialized foil + 3D set/drapes enclosing 3 sides and lighting and audio as required and whow controller (on site or remote)
Subjects are filmed in HDTV and broadcast on to the foil through HDTV projection systems, driven by HD Mpeg2 digital hard disc players, or uncompressed full HDTV video/Beta-Cam players.
