I agree this is awesome... one step closer to Star Wars... busting out the Tie Fighter diagram was brilliant.
Almost 3 years ago I read an article about a system much= like this... but that system had a built-in humidifier and used the moister vapors to project onto.. does this system use vapors or anything as its canvas?
i appologize i read the abstract that was linked but didnt watch the movie before posting...definately cool.. but in terms of practicality for large holographs the projection using vapors is much better than this, but my no means am i putting this thing down.
I do see one issue with this. You'll never be able to have a live person show up on the thing, cause in order to get the frames, you'd need to have a camera spinning around them just as fast. You might be able to use multiple cameras spinning in a big ring around the stage, but you'd practically be creating a tornado in the place. I know they had the guy running at the end, but I'm not completely convinced it wasn't CGI or something that used some thousands of takes of this guy running from various angles.
This is awesome for computer generated stuff though.
Wait, there are more issues: Getting a larger picture would require a larger spinning mirror, again with the whole tornado issues. The moving parts means that it is far more likely to break down, especially at the speeds it's spinning at.
Hmm... I also don't see this working for films, because you won't be able to control the camera angles and stuff, which is a very basic part of controlling the mood and focus of a movie. Stage performances are 3d, but the audience still only sits on one side.
I really love how it looks, but the practical applications are still limited. The moving parts are my biggest worry.
Well - you could just use X amount of cameras to capture a person live and in 3D. With todays CPU power a lot less cameras would be needed since it's possible to calculate a LOT from just to cameras positioned right. So - maybe 4-8 cameras are needed at the bottom, and the same at top.
Also - making the picture bigger has at least 2 things to it. To get X + Y bigger you could just add more mirrors and link these - but getting the Z axis "taller" might be more difficult seeing the picture never goes out of the mirror boundaries :)
yes i know esactly what you mean nick i belive it was called fog screen it used multipul projectors so people could actualy walk through it. i think it was also going to be used in japanese advertisement and sadly it had to be pre-recorded on this demo using hand movements the guy interacts with the image which is pretty cool so im not putting the technology but that fact its a spinning mirror and has to be kept in a glass case is quite sad.

Oh my god, that is nothing short of amazing.

Definitely. Looking at the running man "hologram", I'm strongly reminded of the zoetrope.
