Z-buffer; Depth buffer; Z buffer; W-buffering; Z culling; Z-Buffer; Zbuffer; W-buffer; Depth buffers; Depth test; Depth testing; Depth buffering; Z-culling; Depth-buffer
<graphics> 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.
