Abstract:
A method of displaying a polygon on a horizontal scan display device having a plurality of pixels, the method comprising:A. dividing the polygon into a plurality of vertical stripes that are transverse to the horizontal scan of the display device; B. receiving pixel attribute data for a first pixel in a first stripe of the polygon, each of the remaining vertical stripes having an initial pixel that corresponds to the first pixel in the first stripe; C. receiving gradient data relating to the degree of change of pixel attribute data with respect to the pixel data relating to the first pixel; D. calculating pixel attribute data for each initial pixel in each stripe in the polygon, the pixel attribute data for each initial pixel being calculated based upon the pixel attribute data for the first pixel and the gradient data; and E. calculating pixel attribute data for each remaining pixel in each stripe based upon the pixel attribute data for the initial pixel in each stripe in the polygon.
