DDA Algorithm vs. Bresenham’s Algorithm: Know the Difference
By Shumaila Saeed || Published on February 4, 2024
The DDA Algorithm incrementally plots points of a line on a grid using floating-point arithmetic, while Bresenham's Algorithm uses integer calculations for greater efficiency.
Key Differences
The Digital Differential Analyzer (DDA) Algorithm is a rasterization method used for drawing lines, involving a continuous linear increment of pixels. Bresenham’s Algorithm, on the contrary, is an efficient way to draw lines using only integer arithmetic, thereby avoiding the need for floating-point calculations.

DDA Algorithm employs floating-point operations, which can lead to round-off errors and affect the line's accuracy. Bresenham’s Algorithm, by utilizing integer arithmetic, significantly reduces computational overhead, making it faster and more efficient, especially on hardware that handles integers better than floats.
