Z-buffering is an algorithm used in 3D graphics to determine which objects or parts of objects are visible and which are hidden behind other objects. With Z-buffering, the graphics processor stores the Z-axis value of each pixel in a special area of memory called the Z-buffer.

Different objects can have the same x- and y-co-ordinate values, but with different z-co-ordinate values. The object with the lowest z-co-ordinate value is in front of the other objects, and is the one displayed.
