Parallax
Parallax
is the relative position of the
bodies in the picture, as seen from different points of view.
Looking at a 3-D scene with two
eyes creates two different images one in each eye.
As can be seen in figure 10p1:
-
The far object is seen by the left eye to the left of the near object.
-
The far object is seen by the right eye to the right of the near object.
Figure 10p1: Seeing with two eyes
Our brain is "trained" to interpret these two views
of the same scene as depth in the picture.
In a hologram, each
point on the hologram contains information about a different point of view
of the scene.
