Worldsheet: Wrapping the World in a 3D Sheet, View Synthesis from a Single Image

I wonder how long it takes to generate these images. It's not terribly hard to do by hand with rudimentary 3D modeling skills (i.e the most generous way to describe my own 3D modeling capability), if you know the height from the floor and shooting angle at which the camera took the picture. I've done it with 360 photos (therefore shooting angle didn't matter) in Blender with a VR headset to aid in positioning vertices. You can get results like this in about 15 minutes.

Complex scenes obviously take longer, but results can be extremely convincing for a limited range of view angles.

I learned the technique from this video: https://youtu.be/RSC40B8kHT8

15 minutes. I dont know about this particular technique, but others are in the 10-50ms range. Roughly 20k times faster.

My point is, if you need this sort of imagery, you don't need to wait for Facebook to never actually release a usable product out of this paper. Because that's generally what happens with these kinds of papers.
