Hi All,
I am wondering if there is a way to use 1 or two cameras to make 360 panos in 3D.
Any workflow or special software known to accomplish this with stills?
I know there are some parallax issues at nadir etc, and some other issues, but it should be possible as there are multi camera rigs  (360rize.com, Ozo, Vuze and others) that can do this so it should somehow be possible to do with a single camera with many shots for a static subject ?  I don't need the video at the moment.  
Any tips, suggestions or actual experience creating this type of capture and viewing it on saw the samsung headset?
Its like the holy grail but there is no easy way to accomplish this as far as I know. 
Bryan

It is possible to make stereo panoramas with a single camera if the subject is stationary. You need to use a fisheye lens, take at least ten shots going around the 360 degrees, and be sure to keep the camera level and in the horizontal plane. You will need to stitch crescent-shaped areas of all the images into two  separate images for left and right eyes. The camera should not be rotated about the non-parallax point but several centimeters away from it.

Thomas Sharpless is a master of this technology and has also provided a
helper application:

Yes, Thomas is a master, but I think you will find his helper app for PTgui, which is nearing the end of its beta development, is intended for stereo 3D panoramas taken with two cameras, not a single camera.

Wim Koornneef presented a method on how to do this with just one camera at the Panotools Meeting 2011 in Vienna: http://www.panotools-meeting.com/sessions/how-make-3d-panorama-single-camera-and-ptgui .

Hi Bryan.

Here is a GIF animation that shows the basic shooting approach I use to capture a 3603D stereo panorama using a single camera with a Nodal Ninja 3 pano head + RD16-II Advanced Rotator + a Jasper Engineering slide rail:

http://www.andrewhazelden.com/projects/domemaster-fusion-macros/examples/animated_panoramic_3603D_rig.gif

For each of the left and right equirectangular views there are three fisheye images that are stitched together using a -120°, 0°, and 120° Y axis pan on the tripod.

The stereo 360° tripod cloning and patching work is best done with a program that uses a vector based clone tool so you can re-use the left eye image paint strokes on the right eye view. Here is a screenshot taken in Fusion Studio that shows a node based approach I use for the final processing of the stereo imagery and to paint out the tripod.

Just a side-note: The excellent tutorial by Wim was lacking the
downloads until recently because Wim closed down his site. I asked him
whether he still has the relevant files and as a reaction he contacted
Nick Fanotec, who put the files online and provided a link in the
tutorial: http://tinyurl.com/65hcyua

Thanks to Wim and Nick!
