Abstract
A graphics accelerator interface apparatus for receiving information to be displayed by a computer and the address of such information. Storing the addresses of vertices of a quadrilateral to be displayed by a computer, translating the addresses of vertices of a quadrilateral into signals representing the relations between each of such vertices and the others of the vertices, selectively decomposing a quadrilateral into line segment portions defining trapezoids which bound sets of scan lines, determining the coordinates of the end points of each scan line within such trapezoids, translating the coordinates of the end points into linear values for display, and storing such information for display on a computer output display.
