So, not to refute something that is so clearly incorrect, but I'll add this because work is boring today:
Human 3 dimensional vision is really our brain compnsating for the differences between 2 2-D images. Because our eyes have slightly different perspectives, objects in the image on one eye will be slightly displaced from objects on the other.
As the brain compensates for these displacements, cues are used to determine the distance to objects and their 3 dimensional characteristics. Importantly, we never get truly three dimensional vision, 3 dimensions are just pulled out of 2 overlapping images.
This is how magic eye illusions work. It is an illusion of higher dimensions, much like Kabbalah.
Read all this and more in your introductory perception text books.
