Easy guide to 3D

So why choose 3D?

3D is a fantastic way to get even more from your gaming, movies and apps, find out more below.

• Blockbuster films are now being created with 3D in mind and provide a stunning viewing experience both at the cinema and at home.

• TV channels are beginning to broadcast more and more 3D programmes, including sporting events such as Wimbledon, plus 3D specific film and entertainment channels including Sky 3D.

• 3D gaming has the opportunity to provide even more immersive gaming experiences and 3D opens the door to whole new ways of playing games.

In short, 3D provides more exhilarating, breathtaking and immersive experiences across a whole range of entertainment.

What is 3D?

Our easy guide to 3D tells you all you need to know.

Well, 3D means ‘three-dimensional’; in other words, it’s something that has height, width and depth. Everything in our physical environment, and every movement we make, is three-dimensional. 3D technology takes 2D (two dimensional) images, usually transmitted onto a flat screen, and makes them appear 3D for a real life viewing experience.

Guide to different types of 3D

3D with glasses

Red / Cyan anaglyph glasses

We’ve all seen these; the classic 50’s cheap cardboard glasses and cellophane lenses.

The original 3D glasses that are the least advanced. They use the different coloured lenses to separate the images and present the viewer with a 3D image. Anaglyph is still used in a number of 3D products; however sturdier, better designed glasses are now more commonplace.

Polarized filter glasses

These glasses come in two forms; linear and circular. Linear polarized glasses only work if your head stays in a vertical position.
If you move out of this position, the 3D effect is broken because they work by making one eye see the vertically polarized image and the other the horizontally polarized image.

Circular polarized filter glasses do not work in the same way; you can move your head out of the vertical head position, as a special projector and filter is used to transfer the images.

3D without glasses

Auto-stereoscopic displays:

This method of displaying 3D images is used by modern products such as the handheld Nintendo 3DS and the LG Optimus 3D.

This method is achieved by broadcasting a series of different images in different directions. Generally speaking when using a handheld console, mobile phone or similar product, users will likely be at a certain distance from the screen, allowing this method to work.

Head tracking 3D:

A fairly new technology, this method of producing 3D images relies on tracking the human eye.

A camera or webcam is used to scan the users face and then tracks the movement of the eyes. This allows users to tilt their head, or the device they are using, to effectively ‘see round corners’.

The current limitation with glasses-less 3D is that it can only be used by one person at a time.

Autosterescopic displays such as those found on the Nintendo 3DS can only be viewed from certain angles, and head tracking is limited to tracking just one person’s eye movements.

Shutter glasses:

These glasses use LCD lenses which open and shut alternatively at high speed so that each eye sees a different image. Originally these had to be connected to a power source by a wire that powered the action of the lenses and also synchronised the glasses to the display.

These days, active shutter glasses are powered by small batteries and are synced via infrared signals – much the same as a remote control.

Almost all glasses-based 3D products will include at least one pair of glasses for 3D viewing

The future of 3D

Our guide to 3D has covered the up to date technology. The future of 3D is a little uncertain and with such a variety of technologies being developed only time will tell which method will become mainstream. One thing is clear with manufacturers developing 3D technology at an alarming rate, 3D is here to stay.
