Facebook has begun to roll out a new image feature for social network users, with "3D images" that can give the effect of 3D in a two-dimensional photograph, at to exploit depth maps generated by newer iPhone models.
Originally announced at Facebook's F8 conference in May, 3D images are slowly accessible to all users. The image function provides depth to a normal static and flat photograph, with the background scrolling behind the user while scrolling, panning or tilting the image.
The feature utilizes depth maps made of iPhone 7 Plus and later models, especially using iPhones' embedded "Portrait" shooting feature. By using the two-camera and deep-chart setup generated when the image was taken, portraits can be uploaded to the service with this additional data, which can then be converted to a visible 3D image.
Users must create a new post in the Facebook app, select "3D Photo" from the menu at the top right of the screen, then select the image from the device's Portrait Photo Folder. After selecting, users can enter the rest of the details they want to include in the post before they are sent to the feed.
Facebook starts activating today's feature, with a small number of images that can be created initially, but eventually opens to all users with compatible devices in the coming weeks. While the rollout for creating the images is slow, Facebook allows all users to view 3D images without limitation.
The 3D images will also be visible by users of virtual reality systems, via the Oculus browser for Oculus Go, and in Firefox for Oculus Rift.
