3D Holographic Projection – Best for TIE Fighters
Nope – this is not taken from StarWars but this is from the really real world!
The ICT Graphics Lab at USC has created a low-cost volumetric 3-D display and it looks fantastic.
Apparently (just getting my science-head on) the process utilises spinning mirrors, high-speed DLP Projections, and ridiculously precise calculations that figure out the correct axial perspective needed for a 360-degree image.
 ~PHWEW!~
The process even takes into account a viewer’s positioning.
When projecting video frames into a rapidly spinning mirror, close to 5,000 individual images are reflected every second within the surface area and come together to create a real-space three-dimensional object.
Because these images jump out “toward multiple viewpoints in space,” the USC team created a formula that renders individual projections at different heights, and traces each projected beam back to the display area to find the correct position of the viewer.
As if that wasn’t enough the system also updates itself in real time (200Hz), adjusting to the height and distance of the viewer, producing an image that will “stay in place” – or rather, that “adjusts its projected perspective”.
This, in plain speak, means that every person in the room will be able to have a correct view of a holographic image as demonstrated with the TIE fighter in the very cool image above – no need for cardboard glasses with coloured plastic lenses!
