Which of the following properties is followed by the Bresenham's algorithm?
It is an incremental method
It chooses points randomly
It uses floating point operations
All of the above
Correct Answer :
A. It is an incremental method
Bresenham's algorithm is an incremental method, i.e. we increment one of the coordinates of the point and calculate the other coordinate according to it. In this manner we find all the points of that particular polygon.
