Real world is three-dimensional world, and human eye sees that the image seen during object has a deviation on position, two images it
Between deviation we term it parallaxes.Exactly this parallax, allows one to the distance of difference object, and obtains three-dimensional sense.According to
The different parallaxes of parallax value can be divided into positive parallax, negative parallax and parallax free.When spectators are in viewing：Positive parallax makes one to generate object
Go deep into the feeling of screen；Negative parallax makes one to generate the feeling that object is suspended in outside screen；Parallax free is positive parallax and negative parallax
Boundary, object are just projected on screen, i.e., the zero plane that we often say.For example, the star in summer night sky is from us
Far, the sight that we watch each star is almost parallel, and at this moment parallax is close to zero, human eye be just difficult to differentiate between star and
The distance between we, thus think that each star is similary remote apart from us, an array of stars is seemingly in one plane without three-dimensional sense.
The brain of people is an extremely complex nervous system, and two width for mirroring eyes can be had the figure of parallax by it
