In the scanline polygon fill algorithm, the vertex is drawn for the first edge, since it is a minimum value for that edge, but not for the second edge, since it is a right edge and right edges are not drawn in the scanline Boundary fill Another important class of areafilling algorithms starts at a point known to be inside a figure and starts filling in the figure outward from the point. Using these algorithms a graphic artist may sketch the outline of a figure and then select a color or pattern with which to fill it. **area filling algorithm in computer graphics pdf** cross the area (scan line) Start from an interior position and point outward from this point until the boundary condition reached (fill method) Scanline: simple objects, polygons, circles, . . Fillmethod: complex objects, interactive fill.

It is used in the bucket fill tool of paint programs to fill connected, similarlycolored areas with a different color, and in games such as Go and Minesweeper for determining which pieces are cleared.
