Questions tagged [double-buffering]
In computer graphics - instead of writing graphics information to a part of memory that is immediately render to the screen, the application writes a complete 3d scene to a part of memory called the back buffer. Once all information is in place in the back buffer it is "presented" to the part of memory that gets rendered to the screen. This memory is called the front buffer. By doing this problems like tearing and flickering is more or less avoided.
