- supermatt 3y agoIs a lenticular lens in front of a display really considered a hologram? I thought you needed to actually capture the light wave pattern to be a hologram, whereas a display is just colour and intensity.
- melchebo 3y agoLookingGlass' small portrait display is more like (2D) lenticular. Their larger displays use a micro lens system that directs pixels out in beams in different direction. So you also get parallax in the up & down direction.
- IshKebab 3y agoActually you don't. See this page at the bottom: https://docs.lookingglassfactory.com/keyconcepts/filming-a-looking-glass https://docs.lookingglassfactory.com/keyconcepts/filming-a-l...
- IshKebab 3y agoWell, I didn't know that it was only 1D lenticular (they keep that under their hat!) But let's pretend for a second that it is 2D lenticular. In that case, yes it is absolutely the same as a hologram. Consider this thought experiment. Take a real hologram. Cover everywhere up except a tiny opening - a pixel effectively. Now what information does this pixel encode? It's just colour as a function of view angle. Now do the same thing for a 2D lenticular display. You can reproduce exactly the same thing - a colour that varies as a function of angle. Therefore it is the same. I guess you could consider LookingGlass to be a hologram in one dimension rather than two. Or alternatively it is a hologram if you promise never to move up or down!
