Stereoscopic 3D is a technique of creating the illusion of depth using a stereo image pair.                 
Each image represents the scene as viewed by the left or the right.  The illusion of depth is achieved when the display device (along with passive and active glasses in most 3D systems) is able to present the left image only for the left eye and the
right image for the right eye.  To fully understand how AMD HD3D technology can enable stunning 3D images, it
is helpful to take a look at the Stereoscopic 3D gaming pipeline.

The majority of DirectX® capable games available in the market do not support stereo 3D natively.  This means
that the stereo image pair must be generated separately from the game engine.                     
AMD has relationships with
middleware vendors such as Dynamic Digital Depth and iZ3D, in order to achieve this task of the pipeline.

The middleware intercepts DirectX calls from the game.               
Using these calls, the middleware generates the stereo
image pair, or the left and right eye view.        For certain types of 3D displays, the middleware blends the two views
together to form a single frame using a format that the display is expecting (ex. Row interleave, checkerboard,
side-by-side, etc.).  Once the frame is in the correct format, the middleware instructs the GPU to present and
send the frame to the 3D display.

Thats cool, iZ3D has free support for red/cyan glasses just like NVIDIA's 3D vision.

Im so glad I kept my glasses from shark boy vs lava girl.

Does not say how you get 3D in OpenGL though.

EDIT:
Looks like iZ3D does not support OpenGL games... only quad buffered OpenGL which is only available on the FireGL cards! That sucks cause NVIDIA has supported 3D OpenGL for at least 7 years.
