### Double Buffering

When this option is set to TRUE, there are actually two display buffers: a front and a back buffer. The front buffer is what you see on the screen. When the screen has to be redrawn, such as when the model is rotated, the image has to be erased from the screen and the image redrawn in its new state. The erasing and drawing is done on the back buffer. You cannot see the actual erasing and drawing of the graphics. Once the graphics are drawn to the back buffer, the back buffer is swapped with the front buffer. This happens quickly so that any transition between the two buffers is virtually undetectable.

When this option is set to FALSE, there is only one display buffer. You can actually see the screen being erased and redrawn (albeit very quickly). The erasing and redrawing of the screen causes a flickering.
