Z-buffering

Z-buffering is a computer graphics technique used in 3D rendering to manage image depth coordinates in 3D graphics. It keeps track of the depth of every pixel on the screen to determine which objects, or parts of objects, are visible and which are hidden behind others. By comparing the depth of overlapping pixels, the rendering system decides which pixel to display, ensuring that closer objects obscure those further away. Z-buffering is crucial for rendering realistic scenes with correct object occlusion.
