While it might be possible to somehow spoof what the other sides of 2D person or object could look like in 3D, it would be difficult to do so in real-time.
I think your best bet would be to produce hologram-ready video content first, with holographic playback in mind. For example, in Star Trek: Voyager, it is quite common that a special holographic imaging device be used to capture an image of an object from multiple angles. If that’s what’s being envisioned to be used in the distant future, then it might be true that that’s still a best practice today.
By the way, this forum isn’t about holography, so we’re not going to be subject matter experts here, but your project sounds cool. Best of luck on your endeavor!
