  The Top New Videos list is always full of interesting, current videos. It is always recommended that you have a look through the Top New Videos, but also have a look at these:
  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?

Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

Real-time, interactive 3D Holograms are now a reality.

submitted by therealblankman

Demonstrated at Siggraph "The display consists of a high-speed video projector, a spinning mirror covered by a holographic diffuser, and FPGA circuitry to decode specially rendered DVI video signals. The display uses a standard programmable graphics card to render over 5,000 images per second of interactive 3D graphics, projecting 360-degree views with 1.25 degree separation up to 20 updates per second".

Comment hidden because you are ignoring dag.(show it anyway)

That is so hot.

Seeing that in real life at SIGGRAPH gave me a headache pretty quickly, unfortunately. It strobed a lot. I don't know if the projector was too slow or if the mirror speed was slightly off or irregular. But it's a very good idea.

Help me, Obi-Wan Kenobi...you're my only hope. *bzzz*

Disappointed nobody stuck their hand into the middle of the display to show how "interactive" it is.

lol@theo.

it's awesome, but still so a new technology

This isn't a hologram in the technical sense of the word, "3D projected image" would be more accurate...

Pointless quibbles aside, this is pretty cool tech. I was wondering how the hell you can get a "standard" graphics card to render at 5,000 fps, until I noticed that the bit depth was 1. If I just turn my settings down to 2 colours, I need never buy another graphics card again!

what confuses me is that when you see four rectangles, they are colored.

so, at least in that frame, bit depth is at least 2 (I don't think there were more than 4 colors)
