3d

These images are a example of 3d vision. 3D is based on the way the human brain and eyes work. Because the pupils of a person’s eye are about 6.5 cm (about 2.5”) apart, each eye views a scene from a different angle and generates a unique image.

The brain merges the images to create a single picture. The slight difference between the image from the right eye and the image from the left eye allows the brain to judge the depth. Stereoscopic vision is attained.
