ABSTRACT:
A three-dimensional frame-buffer memory organized into a series of planes each storing one bit representative of a pixel on the display can draw a figure onto one of the planes. The figure can then be copied to preselected ones of the other planes while the first plane is cleared. A bit block transfer can be performed from an "invisible" portion of the first plane to pre-selected ones of the other planes.
