ABSTRACT:
A system and method for storing clipping, masking or stenciling plane data in an unused or residual portion of a frame buffer used with a graphics display. The clipping plane data corresponding to the pixels in the displayed portion of the frame buffer are effectively and efficiently stored through a folding type conversion of addresses. High speed address conversion for both rendering and accessing of clipping data is performed by hardware logic devices.
