Great men studied the principles of stereoscopic vision.
The first man who understood these was Euclid in 208 b.c. He studied the perception of the depth and Leonard in 1584, as well.

In 1840, the British scientist and inventor Sir Charles Wheatstone, invented the first stereoscope, preserved at the Science Museum in London. He showed that our impression of solidity is gained by the combination in the mind of two separate pictures of an object taken by both of our eyes from different points of view. Looking through a central system of mirrors was possible to artificially reproduce the effect of three-dimensional vision.

After 1850 the camera manufacturers created numerous"stereoscopic" devices. The word stereoscopic was created to indicate the ability to represent solid figures (the word is composed of two Greek words stereos "solid" and scopos "looking").

In 1939, View-Master, has been a device for viewing seven 3-D images (also called stereo images) on a paper disk.

All these systems had a great advantage that allowed to reach important results with simple technologies: the audience was a single person who observed the result of the stereoscopic shots. This technique is capable of recording three-dimensional visual information or creating the illusion of depth in an image. The lenses of the cameras must have a distance of 6,5 cm each other, like our pupil

The situation could be more complicated when we want to show a movie simultaneously in the same projection room


"Stereopsis” is the process in visual perception leading to the sensation of depth from the two slightly different projections of the world onto the retinas of the two eyes.

Thanks to our brain processing, we can transform in a “concrete” vision interpolating all our views.

In our opinion, it’s very suggestive to understand that, in different kind of visualization or stereoscopic projection, our eyes don’t see a tridimensional image like the one reflected in a solid bodies, but 2 single flat images
