What is scan line algorithm?
One way to fill the polygon is to apply the inside test. I.e. to check whether the pixel is inside the polygon or outside the polygon and then highlight the pixel which lie inside the polygon. This approach is called as scan-line algorithm.
Determine the advantages of raster-scan systems (i) Rasterisation is now performed faster since a special purpose processor is used. (ii) The CPU is not slowed down by the
