Two opposite screens tv rotating. The viewing angle must be as smaller
as possible (for example 1 degree). The TV should rotate at 12
turn/second, so 24 times a second you can see a screen . A processor
will change image on each screen every time the TV turn of 1 degree,
so a single side of TV
should have a refresh of 4320 Hz (12 turn/second
* 360 degree).
So you can see a video on TV that change prospective based on the
angle you look at it, without special glasses or sensors.
A greater viewing angle decrease the refresh rate, but damage the
overall experience.
PS: a multiangle video is needed..

to "keep your dog style" you can use an exagon (6 screen
instead of 2) and slow down to 4 turn/second |

I think it shoul be used with computer generated films.. |

The rotating leds device in the link reminds me of a cheap gyro powered flying saucer toy I picked up from a "pound shop" over 20 years ago. Despite never changing the batteries, it still works, managing to generate an amazing number of patterns from a single row of leds running along a radius line from the edge to the centre of the rapidly rotating saucer. The initial power is provided by a toothed pull strip that engages with a cog at the centre of the centre. It's a brilliant toy and I'm surprised that it's no longer around. Will try to find a link. A full "3D" version would be totally excellent. [did search - found similar, but none as basic, elegant and simple - I may try to video the one I have] |
