Line Algorithm Comparator

Compare DDA and Bresenham's line drawing algorithms pixel-by-pixel on a zoomed grid. Step through each decision, inspect the Bresenham pₖ parameter live, and watch both algorithms draw side by side.

Module Objectives

  • 1
    Understand how DDA uses floating-point parametric increments
  • 2
    Master Bresenham's integer decision parameter pₖ and its update rule
  • 3
    Compare pixel choices between DDA and Bresenham for the same line
  • 4
    Recognize why Bresenham is preferred in hardware rasterization
