NOTE: Google Cardboard camera does not generate full spherical panoramas. Google Cardboard Camera is only capable of generating a 360 horizontal cylindrical panorama. The panoramas it outputs will not encompass both the floor and ceiling of an environment. When the final panorama is output from the following process, the resulting image is a full stereo spherical panorama where the "missing" areas of the image are filled in (by Google) with a blurred version of the actual horizontal slice. The final single output image is composed of the left eye 360 panorama (with blurred "extensions") stacked on top of the right eye image.
The following image shows you how the composite stereo panorama is composed:
- Take picture with Google Cardboard Camera app (https://itunes.apple.com/us/app/cardboard-camera/id1095487294?mt=8) on your IOS device.
- We recommend starting your capture 180 degrees from where you want the scene to be centered. For example, if you are taking a photo of the exterior of a building and you want the scene to be centered on the front door of the building, you should first start taking the photo looking away from the front door. If you don't have the luxury of controlling where you start, you can always adjust the starting orientation from the Visual Vocal authoring portal. Information on adjusting panorama rotation is available in the Setting The Point Of View For Teleporters: Setting The Rotation Orientation article.
And unlike other panoramic capture applications, it's also best to take the image with your phone held some distance from your body so that you are not rotating around the center of the phone. It is best, in order to get some degree of stereo separation, to make sure there is a good amount of parallax image shifting as you pan around to take the photo.
