Light field rendering: a quick diagram

Been reading about light field rendering for free movement around 3d scenes captured as images. Made some diagrams to help it make sense to me, as one does…
 
There’s some work going on to add viewing of 3d models to Wikipedia & Wikimedia Commons — which is pretty rad! — but geometric meshes are hard to home-scan, and don’t represent texture and lighting well, whereas light fields capture this stuff fantastically. Might be interesting some day to play with a light field scene viewer that provides parallax as you rotate your phone, or provides a 3d see-through window in VR views. The real question is whether the _scanning_ of scenes can be ‘democratized’ using a phone or tablet as a moving camera, combined with the spatial tracking that’s used for AR games to position the captures in 3d space…
 
Someday! No time for more than idle research right now. 😉
Here, enjoy the diagrams.
