Questions tagged [stereoscopy]

Stereoscopy refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer.

Stereoscopy refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer.

This technique is distinguished from 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye movements.

How do I output 3D images to my 3D TV?

I have a 3D TV and feel that I would be shirking my responsibilities (as a geek) if I didn't at least try to make it display pretty 3D images of my own creation! I've done a very basic amount of OpenGL programming before and so I understand the…

How can I output a HDMI 1.4a-compatible stereoscopic signal from an OpenGL application to a 3DTV?

I have an OpenGL application that outputs stereoscopic 3D video to off-the-shelf TVs via HDMI, but it currently requires the display to support the pre-1.4a methods of manually choosing the right format (side-by-side, top-bottom etc). However, now I…
