DDA

1. How does DDA algorithm work?

  1. First find \delta x and \delta y.
  2. Determine which one is greater( \delta x or \delta y)
  3. if (\delta x is greater) set steps = \delta x
    1. x will be increament 1 in every step
    2. y will be increament by m$\delta x$ + b
  4. else set steps = \delta y
    1. y will be increament 1 in every step
    2. x will be increament by $\delta y$/m – b
- It is an increamental scan conversion methods [^1]
