Yep, I was thinking about a lenslet array system with NxN subpixel under each lenslet. The subpixels are view dependent by emitting light directionally using fish eye magnification of the lenslet. For 64x64 subpixel resolution (giving you around 256 view angles), you need a total of 512 megapixels for a 1080p lenslet array.
