Any multi angle 3D image should produce lightfields, only question is - how? Is that holograms, lenticulars, tensor or something else - you need to produce 4D lightfield (to see 3D from every single point of view) with some thin-film technology. Otherwise it will not work. Because the future of our world are FILMS. Not a conventional optics and not mechanics and not even tablets. It moves to a pure information. Visible, interactive but not material. So, our thin lightfield film is the first step to implement it in real life and mass-use. We are trying to remove boundaries between object and image. And before we completely remove any material carrier of information, we should film it.
