Which of the following line-generating algorithms is the most effective and efficient?
Midpoint algorithm
Bresenham's Line algorithm
DDA algorithm
None of the mentioned above
Correct Answer :
B. Bresenham's Line algorithm
Since it only requires integer addition, subtractions, and multiplication operations, Bresenham's line algorithm is a quick process. These operations can be completed easily, allowing lines to be produced quickly.
