Hi Kevin, Paul and Fred:
Thank you all for your valuable suggestions!
However, in the following code:
public void render()
{
if (gc == null)
{
gc = canvas.getGraphicsContext3D();
view=canvas.getView();
grt1=grat1.getGrating();
}
view.setMinimumFrameCycleTime(X);
gc.setBufferOverride(true);
gc.setStereoMode(gc.STEREO_BOTH);
gc.clear();
gc.setStereoMode(GraphicsContext3D.STEREO_LEFT);
gc.draw(grt1);
canvas.swap();
}
No matter whether I set the value X in view.setMinimumFrameCycleTime(X) to
be 1, 2, 3, 10, 20 or 50, the ghost image existed the same. When X=0
(default value), the ghost image exists, then increasing the FrameCycleTime
could not help decreasing the ghost image (because the ghost image will last
longer), am I right? If changing FrameCycleTime did not change the
appearance of the ghost image, what is the purpose of setting
view.setMinimumFrameCycleTime(X)? Do I need to change some thing else to
minimize the ghost image? As Paul said, the frameCycleTime depends quite
upon the OP, is there any method to change the FrameCycleTime of an OP (I am
using Win2000)? Since the persistence of a monitor is unchangable, how to
reduce the FrameCycleTime has become crucial to my experiment. I have to
keep consulting you until I have a solution.
Thank you all for your great help!
G.B.
