Virtual Labs

a: To minimize the number of comparisons during the rasterization process. b: To ensure edges are processed sequentially as the scanline moves downward. c: To group edges that belong to the same polygon together. d: To prioritize horizontal edges over vertical edges.

2. How does the Scanline Algorithm handle edges that intersect at the same scanline during rasterization?

a: By processing edges from left to right based on their x-coordinates. b: By discarding one of the edges to avoid overlap. c: By merging the intersecting edges into a single edge. d: By using the parity rule to determine which pixels to fill.

3. What is the significance of incrementing x-coordinates by 1/m during the scanline filling process?

a: To calculate the slope of the polygon's edge. b: To ensure the Active Edge Table (AET) remains sorted. c: To track the intersection points of edges with the current scanline. d: To adjust for changes in the polygon's color intensity.
