an array used to store the maximum z coordinate of any feature plotted at a given (x, y) location on the screen, used for hidden line removal in a 2d rendering of a 3d scene. the z axis is perpendicular to the screen with values increasing toward the viewer so that any point whose z coordinate is less than the corresponding z-buffer value will be hidden behind some feature which has already been plotted.
