DDA Line Drawing Algorithm vs. Bresenham Line Drawing Algorithm: Know the Difference
By Shumaila Saeed || Published on February 26, 2024
DDA Algorithm uses floating-point operations to draw lines, while Bresenham’s Algorithm uses integer arithmetic for more efficiency.
Key Differences
The DDA (Digital Differential Analyzer) Line Drawing Algorithm incrementally plots points along a line's path based on a linear equation. It uses floating-point operations, leading to a slower performance than Bresenham's Algorithm, which employs integer arithmetic to efficiently plot lines on raster devices.
