Facebook made a small but interesting announcement at the end of its F8 keynote today: you’ll soon be able to post 3d photos to your newsfeed … How exactly Facebook will pull this 3D effect off, which looked pretty good in today’s demos, but also quite limited in how「3D」these photos actually are, remains to be seen … What’s most likely, though, is that Facebook will use some of its machine learning smarts to power some of this, especially given that the company also announced its (somewhat odd) ‘3D memories‘ feature today which uses machine learning to recreate the scenes of old photos in VR.
