Which of the following algorithm is a faster method for calculating pixel positions? a) Parallel line algorithm b) Mid-point algorithm c) DDA line algorithm d) Bresenham’s line algorithm
Correct choice is (C) DDA line algorithm To explain I would say: The DDA is a faster method for calculating pixel positions.because it uses realarithmetic (floating-pointoperations). DDA algorithm in line drawing because it performs only addition andsubtraction in its calculation and usesonly integer arithmetic so it runssignificantlyfaster.
