Thanks to eye tracking you don’t lose 3D when you move, but the angle of the image remains the same and the image stretches or crushes while you move, just like with 3D with glasses (the animation does not accurately represent the perceived effect)Īll this becomes much more complicated if we take into account the separation recorded for each scene and how this distance increases or decreases according to the size of the screen, then that is related to the fact that the eyes converge at different distances from the 3D image while in reality they are always focusing on the distance to the screen.

If we are one meter (three feet) from the screen the sword and the arm will seem very short, however if we move several meters away from the screen the arm and the sword will seem excessively long. Consequently, if in the image we see that the head of the protagonist is slightly inside the screen this will continue to be fulfilled whether we are near or far from the screen. If we watch this scene close to the screen the brain will not have much trouble detecting the edge of the sword very close to the eyes, if we go very far from the screen the brain still sees that this sword is at the same distance from the eyes (that distance was fixed when recording the two points of view for each eye). We can explain it with an example if we watch Beowulf‘s memorable scene in which the hero points the sword at our eyes.
