Viewing 3D Pictures with the Parallel method and Cross method Because our eyes are positioned about 6 to 7cm apart, each eye sees at a slightly different angle. The brain processes this difference to produce a three-dimensional image. This principle is applied to taking and viewing 3D pictures.

3D pictures can be viewed by the Parallel method, where the left and right lines of sight are parallel (like looking far away), or by the Cross method, crossing the lines of sight. Viewing a 3D picture without the viewer may take some practice.
