If you want it to be holographic rather than just 3d (which I assume since you do because non-holographic 3d is already trivial with VR) you either need to render in real time which means toning down the rendering requirements by a few orders of magnitude or use light fields which means much more prerendering and absolutely bonkers file sizes.
