The info and scripts from @dithermaster and @lonetech are a great way to explore the way the LG works. I wanted to get even more basic, by using a quilt image that shows the view number (low view number = view from the left, high view number = view from the right):
Btw, the script that generated the image can be found here gen_numbers_quilt.py and has some parameters for other quilt layouts (e.g. 4x8, lower resolution, etc).
I could not find a way to add my own lightfield pic to the Library app, so turned the image into a one-frame mp4 movie and used the mpv shader by @lonetech to play it on the LG (small model). I assume that reproduces the “official” method for displaying content. Oh, and trying to analyze the patterns really screws with your head
I’m wondering about the “inversion” that seems to happen when the viewing distance becomes more than 55 cm (give or take). When viewing closer than than (only one eye open and holding a static view position) the view numbers generally decrease from left-to-right over the display, which seems to make sense as you’d expect to see views more from the left on the right side of your viewpoint. But when farther away the view numbers increase from left-to-right. I guess because your eyes in that situation still get correct relative view positions it isn’t disturbing (e.g. left eye: 21-26, right: 24-29 and therefore left-most, respectively, right-most).
