You can form this hologram trivially by considering each pixel as a source of rays in a variety of directions. You might then expect a series of hemispherical shapes on the surface, with areas of the dome missing where rays should not be fired. In this case you hit the age old problem of holograms - the sheer volume of information that needs to be encoded onto the surface for a hologram of reasonable resolution to be formed. Whether there is some more subtle surface that reproduces the light field but exploits its compressibility to reduce the surface complexity, I don’t know. Would be fun to try to optimise for it, but alas I have too many things to do already. How does one get grad students?
