Which algorithm is more efficient when drawing lines with a slope greater than 1? a) DDA b) Bresenham's with slope modification c) Midpoint line algorithm d) Wu's line algorithm
Understand the Problem
The question is asking for a comparison of different algorithms that can be used for drawing lines in computer graphics, specifically focusing on their efficiency when the slope of the line is greater than 1. This involves understanding the characteristics of each algorithm under the given condition.
Answer
Bresenham's with slope modification.
Bresenham's with slope modification is more efficient in handling lines with a slope greater than 1.
Answer for screen readers
Bresenham's with slope modification is more efficient in handling lines with a slope greater than 1.
More Information
Bresenham's algorithm includes modifications to efficiently handle cases where the slope of the line is greater than 1 or negative by swapping roles of x and y axes, thus efficiently tracing steep lines.
Tips
A common mistake is not adjusting the x and y increments correctly for slopes greater than 1 in Bresenham's algorithm. This can lead to inefficient line drawing with errors in pixel approximation.
