Mark: Thank you for your comments. You know that ultra-short persistence monitor is very expensive: 4-7 times of the price of a common one. Why can't we do it in this way (in the immediate mode): render a image first and at the moment very shortly afterwards render a black image, to cover off the faded image of the first one which is due to the persistence? If this could be realised, then the images rendered separately to two eyes would be pure: there will be no more cross talk between them. I need to solve this problem because it will save us a tremendous amount of money. In the program I have shown, the black image might be rendered too closely to the first image so that the first image could not be viewed. If you could give me some suggestion about how to let the first image visible before it is covered by the black image, I think the problem will be solved, am I right?
Thanks a lot! G.B.
