What’s a Tomogram?


Last week the world was amazed by CNN’s holograms used in it’s coverage of the U.S. elections.

Turns out the real name for what CNN did is “Tologram”.

Whats a tologram? The National Post has a good article on the technology used by CNN and what the difference is between a hologram and a tologram.


Here is some more information from the article:

The CNN anchors were not really speaking to three-dimensional projected images, but rather empty space, Kreuzer said. The images were simply added to what viewers saw on their screens at home, in much the same way computer-generated special effects are added to movies.
Kreuzer said the images were tomograms, which are images that are captured from all sides, reconstructed by computers, then displayed on screen.
Holograms, on the other hand, are projected into space.
