WebScan-Line Algorithms 1. Find the intersections of the scan-line with all edges of the polygon. • Must be computed in a clever way, or can be SLOW. • Brute Force: test each polygon edge with each scan-line (brutally slow!) • Use edge coherence (many edges intersected by scan-line i are also intersected by scan-line i+1). WebA scan line algorithm for filling a polygon begins by ordering the polygon sides on the largest y value.It begins with the largest y value and scans down the polygon. For each y, it determines which sides can be intersected and finds the x values of these intersection points.It then sorts, pairs and passes these x values to a line drawing routine. the wee center trussvilleWebScan Line Algorithm.
