1+1=4D: Stereoscopic Video in Real Time

In 1993, I discovered this technique using two video cameras, two video projectors and two sets of polarized 3D glasses to create live stereoscopic video. The effect is AWESOME! It must be seen to be believed.

This video only hints at the possibilities. The cameras could be very small and close together creating a stereoscopic view as if one were miniature in a giant world or very far apart creating a 3D view as if one were a giant in a miniature world. Just imagine!

If anyone ever uses the technique I would be thrilled to know about it. I tried to interest the Exploratorium in the idea for possible exhibit development but they passed. With little chance to develop more on my own, I release it to the world.

You're welcome!

Where is the background music from?

@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.

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.

[eyesoare]

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

[LeonardoGulli]

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

[eyesoare]

@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?

@eyesoare

Thanks for the answer.

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.

thanks man.

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
