Exactly!
Seems that you can put the camera side by side, like this:
Should get some gear by next week, will try and keep you posted! 
Oh, that’s a nice hack.
I’m going to contact this guy and see if we can get more info
Dang, would love to upgrade my virtualforest setup with true 3D captures. I’ll keep a close eye on this. Keep us posted Craig!

My understanding is that there are 2 different issues with the 3D captures. The first is to trigger the cameras simultaneously. The second is the combine the two images into a single 3D experience.
Trigger 2 Cameras Simultaneously
The guy in the picture above is using the RICOH remote trigger, CA-3.

That is $40 and may not meet the needs of people that want to trigger two cameras with a Raspberry Pi. So, one thing we can do is to test two THETAs from one computer on two different USB ports. I have two THETA S cameras and can try the test if the community comes out and indicates that it would be helpful.
Merging the two Spheres into One 3D Scene
I had heard that this was difficult to do, but I’ve seen @Svendus build some projects that have a 3D scene. Maybe it’s not so difficult? Would this be a technical problem in your application? Can you match up the two spheres to build a stereoscopic scene?

If I’m not mistaken parallax will decrease to roughly 0 to the edge of each half image. So you lose the ‘effect’ and won’t be able to reconstruct it easily.
So although it will work for most of the image straight ahead from each lens the effect will become significantly smaller progressing to the edge of each circular image. I think you can compensate for this deformation, but it will require some additional math (deformation maps of sorts). Errors will also blow up significantly due to optical deformation compounded by decreasing parallax.
So, it’s possible and worth pursuing for various reasons, but the effect might be nauseating when done crudely. However, I’m enthousiastic non the less.

From my side I am interested in the 3D mode for video, not picture.
So the triggering is not a problem in my case (starting manually recording then sync it on post).
Now I have to figure it out how two make the 3D blending together, or at least, but the video side by side / one on the top of the other, any solution that make YouTube thinks it’s 3D. Any advice?
I’ve shot couple of test with my 2 Theta S, trying different spacing between them to see what is working the best, I can give away footage as well if people want to play around.

I think you may be right. this is good info. About six months ago, I was talking to the THETA product manager about this (he has an engineering background) and he indicated that getting the 3D image would be difficult. At the time, I didn’t understand the reason, but your explanation sounds like a good guess.
I have the email for Katsuhiko Inoue (the guy on Facebook that posted the two cameras) and can ask him how far he’s got. I suspect that he’s only got the center part of the image working. What should I ask him?
It’s not clear what happens when the image is viewed in a headset.
Another idea is for @jcasman and I to search through the Japanese sites for information on these techniques. There’s a sizable number of Japanese researchers working with the THETA on different types of graphics problems. We may be able to find one of their research projects that has a possible solution.

I think you should as how he calculates proper parallax offsets. I’m not sure what the picture looks like if you put it in a 3D sphere and look at it with those tinted glasses. Sadly I don’t have a pair to test this.

It gives 3D effect in two directions
if the thetas are situated East-West the 3D effect
will be strongest North-South
Read-Blue Theta test the greenhouse have a lot of mirror effects
do to the sun
I think the 3D effect are strongest looking North and South do to the camera position West ~ East tripod 1.5 meter apart
click the East ~ West hot spots to see the red blue raw images

I just placed an order for 3 pairs of red-blue glasses for $1.42 and free shipping. Though, shipping might take a while.
It’s a first step in the experimentation.

The effect with my cheap 3D glasses is quite good, surprisingly crisp and realistic. The +100 pixel offset yielded a good effect.
Do you prefer the grayscale look or the color look?
I think the Greyscale are a mistake from my site 
it seems to be a preveiw funktion in the software that create the red-blue efeckt !
Red are normally to the Right
But the embeded Video with the boy on the Tricke, the Blue are to the right
My wife and I tested your site with my cheap red-blue glasses. The greyscale looks slightly crisper.

Any new updates in the 3D area?
Shot some still successfully with 2 theta Z1 but focusing on Theta V with the TA1 microphone repositioned for more accurate ambisonic sound using a custom made extension cable (Good thing we’re close to Akihabara in order to find a 6 pole audio plug/jack!!)
Just curious what any others may be doing. 
This is the latest state of the art.
Most of the people are experimenting with live streaming for telepresence. There hasn’t been too much activity in stereoscopic still images, except to efforts with trying to use two cameras for measurement.
Most solutions to capture a space in 3D use a single camera and attempt to build a point cloud.

Well… I’m thinking of Pre firmware update perhaps where there was little to no stabilization.
My theory is that the stabilization won’t be exact same for 2 cams and could prove uncomfortable for the viewer’s eyes.
re: “This is the latest state of the art.”
Wow! That’s pretty fascinating! Not quite what I’m trying to do but gives me more ideas!
You may be able to experiment with turning off Zenith Correction and changing the stitching. I don’t know too much about 3D stereoscopic photography. The information below might be irrelevant.
