Abstract:
1. A computer-generated method for rendering an image on a display, comprising: a processor redefining a primitive surface to create a redefined primitive surface, said redefining comprising clipping a first edge of said primitive surface to a second edge of a displayable screen area, said first edge of said primitive surface extending outside a guard band region prior to said clipping, said guard band region surrounding said displayable screen area, wherein said redefining further comprises clipping a third edge of said primitive surface to said second edge of said displayable screen area, said clipping of said third edge causing said redefined primitive surface to have a second vertex that said primitive surface does not have, said clipping causing said redefined primitive surface to have an edge running within said guard band that said primitive surface does not have; and, the processor scissoring said redefined primitive surface with graphics processing logic circuitry.
