i have written a object selection algorithm which picks the objects by there color. i give every object an unique color and then i just have to use the glReadPixels method to check which object was selected

this works fine and is really fast but the problem is that the frame is displayed on the screen with all the picking-colors so the screen flashes every time you select something.

so my question is: how do i write everything in the correct display buffer but dont display it on the screen to avoid these flashes?
