PREVIEW / Hacking Facebook 3D Photo using Blender and Animation Nodes
Basically you need to generate image render with Depth Map data, which is the Z-depth render. Then you use Depth Cam app to embed the depth map and generate 3D Photo that Facebook will hopefully understand to generate its “3D Photo” effect.
There are few limitations and gotchas that I need to talk about in a proper tutorial. Let me know if you are interested.
