You’re not seeing things — that photo in your Facebook newsfeed is 3D. Launching today, 3D Facebook Photos use the depth maps from dual-lens smartphones to add dimension to an image as you move your phone. The effect is an image that pops as you scroll, without any specialty gear (unless you want to use your Oculus).
Like moving a smartphone to pan around a Facebook panorama, 3D images in Facebook will respond to the movements of a mobile device — creating movements in the photo that give the image a sense of depth. The format is also compatible with the Oculus Browser on Oculus Go and Firefox on Oculus Rift.
