Looking Glass 8K Immersive Display

You can get a lot done with re-projection and temporal anti-aliasing. At the most abstract level you can consider it an encoding problem: given an image, what's the marginal entropy of a slightly deviating image? There's very little that actually needs to be uniquely computed.

Edit: If you're willing to give up strict coherence between views you might be able to do even better.

I'm pretty sure it's a lenticular display, so if it's running a standard 8K panel (~33 megapixel), your effective resolution is under 1 megapixel per angle.

Computationally, generating 33 megapixels spread across 45 views is very similar to generating 33 megapixels in one view, so if your rendering pipeline can do standard 8K, you should be fine.

A training set for this could be created from VR paintings. We have the full spatial painting and we can create as many 2D views as we want from it.
