These glasses allow the left eye to see everything that is not red and the right eye to view everything that is not blue. The application then draws the scene twice, once so that it is only viewable by the right eye in blue and simultaneously a second time, in red, for the left eye. Here both frames are rendered simultaneously, so there is no refresh rate issue. The biggest disadvantage however is that the feel of true colors is lost. In both techniques cross talk can occur. For the case of stereo vision, this is explained in chapter 2.3. \\ -With the additional head tracking information, the red-blue images can be improved.
