What is the primary disadvantage of the DDA algorithm for line drawing? a) uses floating point algorithm b) cannot draw vertical lines c) limited to octants d) cannot handle slopes greater than 1
Understand the Problem
The question is asking about the primary disadvantage of the Digital Differential Analyzer (DDA) algorithm, which is used for line drawing in computer graphics. It lists several potential disadvantages, and we need to identify which one is the primary disadvantage.
Answer
It cannot draw vertical lines.
The primary disadvantage of the DDA algorithm for line drawing is that it cannot draw vertical lines.
Answer for screen readers
The primary disadvantage of the DDA algorithm for line drawing is that it cannot draw vertical lines.
More Information
The DDA (Digital Differential Analyzer) algorithm struggles with vertical lines because the slope becomes undefined, leading to inaccuracies.
Tips
One common mistake is assuming DDA can handle vertical lines when, in fact, it leads to undefined behavior due to infinite slope.
