A display list (also known as a display file) is a collection of graphics commands that define an output image. By executing the commands to combine various primitives, the image is created (rendered). This activity is typically performed by specialised display or processing hardware that is partially or entirely independent of the system’s CPU in order to relieve the CPU of the overhead of maintaining the display and may provide output features or speed that exceed the CPU’s capability.
Display Processor Silent Features:
- Display processors perform tasks like generating different line styles, displaying colour areas, and performing transformations and manipulations on display objects.
- The GPU was used before the display processor (Graphics Display Processor).
- The most common CRT-based display device is the video controller (Cathode Ray Tube).
- In addition to the system memory, the Display Processor has its own memory area.
“Display List” Is A Display File Interpreter In Computer Graphics
- A display list is a type of graphics command that produces an image as output.
- The image was created by running the command.
- This can be done by either the specialised display or the system CPU.
- This display list is available in both 2D and 3D dimensional scenes.
- This display list will be used by the system to save the scene known as retained-mode.
- The Atari 8-bit family was the first popular system with a true display list.
- It contains the ANTIC series of instructions. It is stored in the computer’s memory and is executed in real-time by the ANTIC.
