How does the midpoint line algorithm determine the next pixel to be drawn? a) comparing the midpoint to zero b) calculating the slope c) comparing the midpoint to the decision parameter d) using a random number generator
Understand the Problem
The question is asking about the method used by the midpoint line algorithm to determine the next pixel in a line drawing process. It is looking for the correct choice among several options about how the algorithm makes decisions.
Answer
Comparing the midpoint to the decision parameter.
The midpoint line algorithm determines the next pixel to be drawn by comparing the midpoint to the decision parameter.
Answer for screen readers
The midpoint line algorithm determines the next pixel to be drawn by comparing the midpoint to the decision parameter.
More Information
The midpoint line algorithm is an efficient and accurate way to render lines in raster graphics by approximating the ideal line slope through incremental error checking using a decision parameter.
Tips
A common mistake is to confuse the algorithm with simple slope calculations; remember, it uses a decision parameter for each iteration.
