Pixel Buffer

Definitions

1. A contiguous block of memory that stores raw pixel data (color values for each pixel in a grid) representing a frame or texture. In OpenGL it's called a Pixel Buffer Object (PBO); in macOS/iOS, CVPixelBuffer is used for video frame processing.

   In plain English: A chunk of memory that holds the color of every dot on the screen, used by the graphics system to draw images.

   Example: "We double-buffer the pixel buffers so the GPU can render into one while the display controller reads from the other, eliminating tearing."
