I started thinking right before I went to sleep last night and I was trying to figure out a way to have a home theater but in 3d. Like anything you watch: 3d.

I was thinking, you would need:

#2 of those new EVO projectors.

#Those polarized glasses to see in 3d.

#A lens-like device (I don't know the name for it) that is placed just in front of each projector that polarizes the light to work with the glasses. It turns on and off at 144 times a second. I can't imagine those being all too expensive. I've seen them before (if you know the name of the device help me out here).

#And finally, a computer, or even 2 computers, to play the video at the exact same time in sync.





I know what your thinking.......it won't work because you need each video feed to be of different perspectives. One image/video projection for the left eye, and a different image/video projection for the right eye (the perspective of the image would be off by an 1 or 2 inches to replicate the depth perception just like human eyes).

Thats basically the most important part.





Now with that given, I can't see any reason why somebody hasn't yet developed a program or software that allows you to take one image/video (left eye) and process it to render out another image/video just the same except its from the perspective of the right eye. Instand 3D! That would be sooo much easier I think than everybody doubling up on cameras to achieve 3D. And cheaper too.

I don't know if there currently is software like this out there. If there is, let me know
It should also be a streamlined process too, or at the most take as long as burning a DVD-R.


The reason I thought about this is because I saw a program online that takes any 2D image and turns it into a 3D model. That was awesome. Now if we're able to do that SURELY we can do what I'm talking about.

If anyone on these forums has the technical know-how to develop such a program you already got 20$ from me. I'm sure everyone else here would agree.

Polarizing sheet film is cheap and easy to get, and make your own polarized glasses.

Ohh OK some interesting stuff there.

Lets say though that we do in fact have a silver screen to maintain the polarization.

And also lets say that we take the LCD panels from both projectors and remove the polarizing sheet then replacing it with your own to work with the glasses. Surely it should work then.


Mainly its the software I think that needs to be made though.

no but I'm not talking about the red and blue glasses.

I'm talking about polarized glasses, just like in current 3d Cinemas.

It seems like what youre trying to do is make it so the left eye only sees the left PJ, and right eye only sees right PJ. Sounds like a neat idea, and I think since the projectors already output polarised light, you would not need this device youre talking about, however you would need to rotate the polarisation of one projector 90 degrees, and would also have to make your own glasses(probably) to ensure the polarisation is correct.

Maybe I'm wrong, but it seems like the glasses that you wear would need to be in exactly the same orientation as the projectors polarizers. I don't think you could do it with out restricting the minute movements people do all the time. Now maybe if the polarized glass was stationary and swung around in front of each eye, I could see that working.

Well, let us not say "wrong", I'll settle for "incorrect" or "not right"

I have done it, and if you search these forums for a guy from spain with 2x DIY 19" PJ's (1440x900 res!?!?) he has done it too, he is the one to ask for software, he is also using B*ttorrent to distribute movies he has already run through his software setup.

I only did it for Gaming, NFS looks so sick, games are awesome in 3D!

Basically pick up a set of $3 plastic glasses from http://www.berezin.com/3d/3dglasses.htm#Polarized and use them with a set of 45 degree polarized PJ's (many LCD's are 45/135, some are 90-180, which won't work) , you will need to mirror one PJ to flip the polarization 180 (aka from 45 to 135) for the other eye, but the software can account for that, Nvidia control panel for Stereoscopic drivers will do it natively .

If you browse my topics you can find tons of info about it, and links to cheap stuff. I got rid of my eVo(s), and I might try this again if I build some DIY's.

Basically you will need a silver screen (I have posted the cheapest sites on here many times) and just two LCD projectors and a Mirror, FS is preferred, but I used one from the local drugstore and it was fine.

I eventually went to a dual 17" direct-view setup with a half-silvered mirror (maybe that is in mad Science, or my eVo topic), just for the quality and portability.

If you want to game you will need a single 7900 series card right now, the 8800/8600 aren't supported, SLI isn't supported. I have successfully used a 6200/6600/7300/ and 7900 card to do this, but the 7900 handled it best because of the 256MB GDDR3 and the 20 pixel shaders, they are around $120-150 on ebay. If it is just for movies a 6200 should do it for about $30-40.

I am glad to see people are still thinking, just this morning I was imagining a pair of box PJ,s, one a straight shot and another mirrored internally, and making an angled corner on the straight-shot to let the triplets be very close together, and then hinging them at the corner so there is only one horizontal adjustment screw needed to line up the projections .

Happy hunting, PM me if you need more info, but I am on dialup (trying to kick the internet addiction, I was on for ~8-12 hours a day before I cancelled the DSL), so it may take a little while for me to get back to you.

yeah thats exactly what Im saying with the polarized light. have matching polarization on each projector and glasses.

thats the easy part.

but if you have both projectors playing the exact same image/movie perspective it won't look 3D. You need one video/perspective for the left eye and another video/perspective for the right eye. What I want to find out is if there is software out there that can do this, and if theres not, why hasn't it come out yet and when would it come out?

Oh true! So you have actually done this. I gotta check out your posts and the guy from spain. Where can I find him?

Here is his plog, he has the movie software, I only played video games on my setup.
