Perspecta Walk Around 3D Display

Spinneyhead writes "New Scientist reports on the Perspecta display, a goldfish bowl like device that displays moving images in such a way that they seem to "float" within the display. "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".""

so now I'll finally get to see that Leia message?

You'll find the company here:

Does it say So long, and thanks for all the fish along the brim?

I had a look at one of these once

[BabyDave]

The lady who was operating it said I'd meet a tall handsome stranger. Luckily she didn't ask me to cross her palm with $40k (that's a heck of a lot of silver).

Cool, but kind of small

[Anonymous Monkey]

I read the atricle, it sounds realy cool. But isn't 12cm kind of small for use in air trafic controll. "sorry, i can't see your blip because it's behind another blip" I think screen flicker isn't as bad of a thing as size.

Arrgh, Refresh rate!!

From the article:

turns at 15 revolutions per second, sweeping out a solid white sphere.

I definitly don't want it until they get up 85 revolutions per second, and probably more. And I thought that 60 was horrible, imagine what 15 Hz would look like.

Pictures (flat)

How does it work? A spinning screen, must be transparent I guess... what's the sci-fi sphere for?

Has to remain small scale for now...

[A Dafa Disciple]

The product in TFA is only 25cm in diameter, and if the featured image of the display is up to scale, then its display dome is going to be about 20cm in height. I can't imagine the display of this thing can be too good from underneath with the bottom of this device in the way. It is also stated in TFA that, in order for this thing to work, the screen on the inside has to spin at 15 revs/sec.

You can imagine the complexity of this device as it grows in scale. Even having a version of it at double the width and height is going to cause issues in trying to control the stability of all of its components. The velocity of the outermost edge of the screen (closest to the enclosing dome) is going to increase significantly as the device increases in size. All the while, you're creating a tornado within the dome.

I'm afraid that large scale versions of this device are going to be infeasible in functionality, production, and especially cost (this baby version costs 40 grand) as many complications are going to arise.

"I still can't figure out how this gives the appearance of 3D. Can someone explain this for the physics-challenged?

Take a flashlight. Tie a string to the end, go out at night and spint it around really fast by the string. It looks like a circle. That's basically it.

Movie

[panxerox]

I dont know why it sounds like a jet taking off but heres a movie
