WebThe scanline fill algorithm is an ingenious way of filling in irregular polygons. The algorithm begins with a set of points. Each point is conected to the next, and the line between them is considered to be an edge of the polygon. The points of each edge are adjusted to ensure that the point wih the smaller y value appears first. graphically ever after
