Really the rows are indexed in 1024-line frame buffer memory as the top 496 lines for the left eye and the bottom 496 lines for the right eye, but translation to that indexing scheme is straightforward. The corresponding right-eye pixel PxyRc produces the crosstalk. For the StereoGraphics CrystalEye right eye view compensate for crosstalk from the left eye view by exchanging L and R in the expressions above. The worst-case was an image covering the screen with no background showing through. Phosphor afterglow seems to cause much of the crosstalk, especially at the bottom of the screen, where most crosstalk occurs with active glasses.
Speed is in a practical range in some cases.
