A pair of specially-captured images can appear as 3D, even though the images are actually flat. This technique, called stereoscopy, creates the illusion of depth in otherwise flat images or videos by essentially tricking your brain. Try these.
Try crossing your eyes and making the two images overlap; this is called freeviewing. Slowly bring the two images together into focus and you should eventually see the image in 3D. You might need to move your head closer to the screen.
Don a pair of red-blue (or red-cyan) 3D glasses to view the above image. You should see the sign appear in 3D, with Mount Stuart in the far background.
The Vislab uses lightweight, passive 3D glasses to display 3D multimedia, similar to watching movies at the cinema and modern consumer 3D televisions. It’s much easier on your vision because you don’t need to cross your eyes. You don’t need retro-coloured glasses, so you can view in full colour.
Check out our 3D photography library for different pictures from around campus. They were taken on an iPhone, without alignment or guides, so they’re just a taste of what’s possible.
You’ll need software such as StereoPhoto Maker (SPM; free download, Windows-only at present) to open and display the images in a 3D format you are capable of viewing. SPM is flexible and can output in essentially every stereo 3D format in existence.
