A display list processor is a sequence of commands that instructs a computer on how to draw an object on the screen or output device. They are primarily used in computer graphics to improve the speed and efficiency of rendered scenes and make programming code easier to understand. Many software and hardware systems use display lists such as vector-based graphics editing software, some game console systems, and specific computer graphics libraries.
The Amiga computer also uses a similar feature in its hardware called the “Copper.” It is a co-processor that runs a simple program or “Copper List” to modify the hardware registers with the display while running in sync. This system was very sophisticated for its time, and once instructed to generate a display mode, it automatically generated a display for each successive scan-line.
A display list processor can represent both two- and three-dimensional scenes and can be executed every fraction of a second to maintain and animate the output in case of display devices without image buffers. However, in modern systems, the commands need execution only when they have changed or updating the output. They can be used in maintained-mode systems, unlike instant-mode systems.
What is a display list processor?
A display list processor is a sequence of commands that instructs a computer on how to draw an object on the screen or output device.
What is the purpose of using a display list processor in computer graphics?
The primary purpose of display list processors in computer graphics is to increase the speed and efficiency of rendered scenes and make programming code more comfortable to understand.
What other systems use a similar feature to a display list processor?
Other systems such as vector-based graphics editing software, some game console systems, and specific computer graphics libraries use display lists.
In conclusion, a display list processor is an essential tool in computer graphics that improves the efficiency of rendered scenes and makes programming code easier to understand. It has been widely used in different software and hardware systems, including some game consoles and computer graphics libraries.
