Light-field display vr instead of stereoscopy.
I heard a few display companys develop light-field displays: JDI and Samsung.

displayblocks.org for a recipe on how to build one. I have one light field camera (obsolete Lytro) and one 3D display (Looking Glass).

Itā€™s definitely cool tech, and a neat collection of links, but Iā€™m wondering what the message was? Within headsets, light field tech does not replace stereoscopy; it enables accomodation. Unfortunately it is still somewhat impractical in both rendering technique and sheer data rate.

In media it has a far more powerful role; check out e.g. Googleā€™s ā€œwelcome to light fieldsā€, 8i demos, etc. Light field photos and video permit correct perspective rendering for a userā€™s IPD and position, unlike stereoscopic material.

Lightfields are absolutely the future. But they have to fix fundamental issues with them. Optimizations heavily needed, the fov sucks, Iā€™m sure the refresh rate sucks especially compared the the valve index 144hz. Iā€™d rather take eye tracking to provide fake accommodation for now.
