Where is it implied that 3d means to see all sides of an object?
Its impossible to see all sides of an cube unless your perception is able to bend space, or you have more than one physical perspective which is impossible.
3D = length, height, depth
Doesn't matter that the brain constructs the depth perception from 2 2D images.
The end result is depth perception, ergo a human sees 3 Dimensions.
You are the fucking retard here.
