I am confuded what is 4d about this 3d visualization? What is the camera capturing?
nerdsniper•6m ago
The camera is capturing a 3D projection of a 4D universe. Just as our own cameras capture a 2D projection of a 3D universe.

It's confusing not just because hyperdimensions are inherently confusing to humans, but also because the resulting 3D projection is then reduced to a 2D projection by our computer screens. Just know that the representation is of a 3D projection that you can explore in the same way as any other 3D world inside of a computer game - until you rotate in the ana/kata axes, which will change the 3D universe.
