What is 3D Technology?

When we speak of 3D Technology we talk about stereoscopic vision or Stereo 3D (S3D), which gives a volumetrically impression – not just flat as a drawing or a regular picture or film.

We perceive the volume and distance of objects as our eyes see the world from two slightly different horizontal positions and our brain creates a spatial – three dimensional – impression.

Regular picture and videos which are captured with just one lens show only one perspective to both our eyes and therefore appear flat. Similar as if we would close one eye.

With 3D Technology it is possible to show two slightly different perspectives (one to each eye) to give our brain the necessary information for a volumetric – three dimensional impression.

How does 3D Technology work?

3D Technology uses optical filters to show slightly different perspective views for each eye at the same area (Display or projections surface).

While common 3D Stereo uses glasses to separate the views through different filters for each eye, auto-stereoscopic 3D (AS3D) uses special optical filters attached to the screen showing the different perspectives directly in proper relation to our eyes.

Therefore no special head-ware is required and many people can enjoy 3D images and videos instantly.

In addition glasses-free or naked-eye 3D Displays often use up to 9 views to allow head movement without losing the 3D sight.

The back draft however is that auto stereoscopic 3D Displays have repeating zones in which the 3D effect is reversed – the so called “flip over point”. A proper position and distance to the 3D Display is required, but usually easy to find.
