Depth Buffering

Depth buffering is a computer graphics technique used to determine which objects or parts of objects are visible from a viewer’s perspective. It involves maintaining a special "depth" value for each pixel on the screen, representing how close that point is to the viewer. When rendering a scene, the system compares the depth of new objects against existing ones in the buffer; if an object is closer, it replaces the previous pixel, ensuring nearer objects are visible. This process helps create realistic images with proper overlapping and depth relationships without manually managing object visibility.
