Hi Friends:

The attached are programs for rendering an image to one eye only.  What I am
going to render is a green drifting grating to left (or right) eye.  Because
of the long persistance of the monitor, the other eye (the eye which should
not view the image) will also view a faded image.  That is not what I want
to view.  To black out the faded image, I immediately render a black grating
with exactly the same position as the one before.  However, this second
image (black image) will black out the green gratings completely.  ( comment
off the sentence:   gc.draw(dark); will let you view the green grating). I
tried to use different value at view.setMinimumFrameCycleTime(value) but it
did not work.  To enable you to view what I am saying, in this program the
black image is visible.  Could anyone give your valuable suggestion about
what I should do to show the green grating but reduce the persistance?

Thank you a lot!

G.B. Liu
