Perspecta 3D

[blobrana]

The first 3D display that lets users view 3D moving images is now available.

The Perspecta 3D image system is made up of a circular white polymer screen 25 centimetres 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, sweeping out a solid white sphere.

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 looks to the viewer like a 3D image composed of 100 million `volume pixels` or `voxels`.

As far as I know, this screen works with gas and laser.
But I thought it was 30fps?
Anyhoo, coolness 8-)

Somebody posted a link to this ages ago (well, the other year anyway).

It does indeed use a spinning disc and a synchronised image projection that basically casts constant-angle slices.

maybe it's working on Twos???

(only people who have made animations will understand that reference. oh, well, talking to myself again) :roll:

this looks alot better than those holograms they used to show in museums. this is where every idiot will try to make  gimmicky 3D movies.

Maybe you'd be less talking to yerself if you'd give a brief explanation of 'on Twos' ;-)

oh, gee! NOW you want me to explain my jokes?

what's the world coming to?

 :lol:


(pssst: in the old days when animators used onion paper to make keyframes over LightTables - tables with a light under so you could see through the transparent paper - they would only create every second frame on sequences that moved slowly enough. therefore, a second of animation could require 15 drawings instead of 30.

and as the really old stuff was done for film, a second was 24 frames which could be cut down to about 12 drawings.

At that point they would transfer the drawings by painting on cels [celuloid]. As this work was obviously very involved, anything that made it just a bit faster and more efficient was a good thing.

ergo, "working on Twos")

One always has to explain his/her jokes to me :-/ . I just give up asking, also because I don't want to spoil the joke for the others...

Hum,
its not funny when you have to explain the joke.
