Developments in 3D cinema
When the first 3D films were released in cinemas, 3D glasses were still a cool accessory. Today, if you want to watch a three-dimensional blockbuster in the comfort of your own living room or at the cinema, the glasses are more of a nuisance. They are a particular problem for people who wear glasses, and for other viewers they can even cause headaches - and nobody really needs that during a relaxed evening at the cinema. But watch out: 3D glasses could soon be a thing of the past and find their way into the rubbish bin!
Cinema 3D technology
The keyword for the method used by the research team to develop the project under the name "Cinema 3D" is autostereoscopy. In this method for displaying three-dimensional images, two images are displayed simultaneously.
So-called parallax barriers (inclined strip masks or lenticulars) ensure that the light from the individual pixels is directed in different directions. In this way, the viewer sees a different view of the scene with each eye. Aids such as 3D glasses are no longer necessary with this technology.
Until now, independent 3D formats were only available for televisions, but could not be used for cinemas and therefore for multiple viewers. To ensure that this method now also works on the big cinema screen, the team relies on multiple parallax barriers and uses additional mirrors and lenses. This gives the viewer the right view of the scene, regardless of where they are in the cinema.
