An algorithm used for painting 3D scenes to a 2D plane (like a computer screen or piece of paper).

In brief, it sorts the elements of the scene by distance from the viewer, and paints the most remote objects first. Then nearer objects will be painted on top of more remote objects, and you don't need to calculate which parts of the remote scenery would be visible and which would be hidden behind nearer objects.

The algorithm got the name because it is similar to how human painters (of pictures, not houses) paint the background first and nearer objects like people on top of the background.
