'''Important Notice:''' Even though it might not pose any danger, try avoiding excessive use of different color paired glasses, and after your flying sessions with the glasses or whatever, let your eyes and brain rest for a while before starting to sew, chop meat, drive 160mph, dig the garden etc. | '''Important Notice:''' Even though it might not pose any danger, try avoiding excessive use of different color paired glasses, and after your flying sessions with the glasses or whatever, let your eyes and brain rest for a while before starting to sew, chop meat, drive 160mph, dig the garden etc. | ||

[[FlightGear 1.9.0]], released Decemeber 22, 2008, marked the release of the OSG version of FlightGear. As of August 2010, most recent stable version of FlightGear uses OSG. For those who are unaware of OSG, it is an open source high performance 3D graphics toolkit. | ||
Stereo vision exploit the human perception by showing a 3-Dimensional image on a 2-Dimensional surface. To understand stereo vision and human judgement of visual distance (that is how we keep visual separation from the traffic), make the following small experiment. While reading this text, close your left eye and then right eye, open left. When you alternate your view, it'll feel like the monitor is moving to little left when you observe with right eye, and vice versa. This situation gives us two different images. Now imagine you took this two "slightly" different images and match it such that each eye sees what it is supposed to see. There are not so many but quite a few ways to achieve this separation. And OSG is capable of doing all of this. Now apply this to your short final 28R at KSFO! | Stereo vision exploit the human perception by showing a 3-Dimensional image on a 2-Dimensional surface.

The easiest and shortest way for users of FlightGear up to version 2.0.0 to experiment with this is to follow the procedure below (quick start). Later versions (including GIT sources) have native support for setting the relevant properties at runtime from a dialog box at View->Stereoscopic View Options. | The easiest and shortest way for users of FlightGear up to version 2.0.0 to experiment with this is to follow the procedure below (quick start).
