ex3buf - Mode-X triple buffering and retrace interrupt simulation. Allegro game programming library. SYNOPSIS
#include <allegro.h> Example ex3buf DESCRIPTION
This program demonstrates the use of triple buffering. Several triangles are displayed rotating and bouncing on the screen until you press a key. Note that on some platforms you can't get real hardware triple buffering. The Allegro code remains the same, but most likely the graphic driver will emulate it. Unfortunately, in these cases you can't expect the animation to be completely smooth and flicker free. SEE ALSO

exupdate - Supporting different screen update methods in a single program. Allegro game programming library. SYNOPSIS
#include <allegro.h> Example exupdate DESCRIPTION
This program demonstrates how to support double buffering, page flipping, and triple buffering as options within a single program, and how to make things run at a constant rate no matter what the speed of your computer. You have to use this example from the command line to specify as first parameter a number which represents the type of video update you want: 1 for double buffering with memory bitmaps, 2 for page flipping, 3 for triple buffering and 4 for double buffering with system bitmaps. After this, a dialog allows you to select a screen resolution and finally you will see a kaleidoscopic animation, along with a frames per second counter on the top left of the screen. SEE ALSO
