Erain in 3D

Each of our eyes captures an image that is slightly different from the other, and in this way creates a binocular vision.

This type of vision enables us to see three dimensions. This is particularly important for 3D movies, in which each frame is actually two superimposed images. As the screen where the movie is projected lacks depth, special glasses are used which allow viewers to see the images separately (one per eye). The brain then integrates the information from both eyes and creates the perception of depth.

The students of 3rd ESO have put into practice this knowledge with a simple experiment: they have made 3D glasses and have viewed photos and videos found on the internet with the keyword “anaglyph”. The experience has transported them to a new dimension!
