Write a short note on Scan-Line Method

Question

Write a short note on Scan-Line Method? Describe with an appropriate diagram?

Answer 1

In this method, as each scan line is processed, each and every polygon surfaces intersecting that line are examined to determine that are visible. Across all scan line, the depth computations are made for each and every overlapping surface to find out that is closest to the view plane. Whenever the visible surface has been determined, the intensity value for that place is entered into the image buffer.
