Say you have a photo, but you want to be able to explore it in 3d so you put it into fortnite but when you move you can't see behind objects because the photo never "saw" behind object.

So you decide to take lots and lots of photos at every single angle possible, but you need a way to link these all together, so you decide that each Centrepoint of the image is a "gaussian". These splat everywhere.

Now you have taken all of these photos and you can now explore the image in fortnite because you took thousands of images of every possible view!

But what if you didn't want to just look at the frozen image in a landscape in fortnite, instead you wanted to use a man dancing in your new upcoming YouTube video called helicopter.

If you isolate this person (let's say taking all these photos on a green screen) you now have a 3d like recording model, you can reshoot and "scene" on-top of something else (like a 3d diarama like in your video!)
