@Andand13 Ah, the music... I made it myself in 1989 using a Casio keyboard/drum loop, improvised guitar and bass and a self-hypnosis tape. It's called "Standing In The Reign" and I hope you dig it.

i did what u did there, i putted one of the cross polarized glasses on front of the projector, but the color started to vary from red to green. i dont get it. is it the type of the projector?
@LeonardoGulli The simplest pair I could find, frames made of stiff paper holding simple polarizing filters set at 90 degrees, per spec. It was obvious that splitting a pair between projectors would naturally match the set I wore. Besides the inherent responsibility I bear by releasing this technique to the public, I'm more than intrigued so WHY do you really need to know?
well i really need to know because in 2 days i will experience this technique at my high school so i just want to have the right kind of glasses on my hands. i dont want to end up like what i did today which was to take the imax glasses and try to make it work. it didnt work with the imax glasses so i was concerned on the right kind of glasses is the right one.
Ok, so taking literally what you are saying is that the projectors are directly connected to the projectors and whala~!
Yeah, I am surprised to that this has not been tried before, good on you for giving it a bash mate. So, if this is as straight forward as it sounds, you should be able to do this with any 2 cameras and any method of projection, 2 sources of each i.e. 2 cameras and 2 projection sources? This seems like an interesting project to start. Just finished building a 3d laser scanner
It appears to be the same technique that's generally used for modern 3D movies shown at the cinema. Except I think they use circular (maybe spiral?) polarisation. Looks like good fun, if you have access to two cameras and two projectors! I don't see what's new, apart from the fact that you are doing it live.
Cross polarization of two film projectors is quite old, but by 1993 no one, to my knowledge, had tried video projectors.
I did it with technology I found at Exploratorium (the projectors had been donated to the Explo by Apple Inc. - the cameras were on loan from TVS/Climate Theater) and now assume someone with unlimited resources had tried it before 1993 but can find no evidence.
Still, isn't the fact that it is live Stereoscopic 3D video impressive? Has anyone ever seen THAT before?
It is impressive, and I wish I had the kit to try it out! Just lacking two cameras and two projectors so far ... oh, and polarizing filters. With modern 3D rendering technology and head tracking, you could create a huge, hologram-like display using similar techniques.
Yeah, the concept is quite easy to grasp and understand. But what about between the cameras and the projectors? Any other hardware/software responsible for interpereting the projected video?
What you see is what you get, so to speak. Light goes into a camera and out a projector. Use a second set and you get stereoscopy, with the addition of the polarizing filter, of course.
I appreciate that this is an expensive rig and know I was very lucky to have the resources available. Still, it confounds me that I hadn't heard of this technique before I discovered it since the technology was fairly old at the time.
This was such a fun project, and such a lovely and relaxing afternoon on Bluxome & 5'th in SF back in '93. Great presentation of the concepts involved, Maestro MJW!
Where is the background music from?

Man!!! u got to help me!
i did what u did there, i putted one of the cross polarized glasses on front of the projector, but the color started to vary from red to green. i dont get it. is it the type of the projector?
what i am doing wrong?
please reply, thanks.

@LeonardoGulli You have to give me more information before I could hope to understand.

Hey, what kind of cross polarized glasses were those that you used to put in your eyes and on the projector????
I really need to know.
thanks

Thanks for the answer.
