Scan line generation is suspended whenever the furthest extent in the Y axis is reached for either edge. The fill operation may be concluded gracefully when such a suspension occurs for both edges, regardless of whether or not it is for the same polygon vertex. The edge machines are equipped...

I also demonstrate the way that uses my new line antialiasing algorithm to implement the polygon edge antialiasing. Again, I provide a hardware implementation design for this polygon filling method.; Fourth, based on the general graphics applications I collected, I provide statistics on the ...
