  • Floating point arithmetic in DDA algorithm is still time consuming.

  • The algorithm is orientation dependent. Hence end point accuracy is poor.

  • Although DDA is fast, the accumulation of round-off error in successive additions of floating point increment, however can cause the calculation pixel position to drift away from the true line path for long line segment.

  • Rounding-off in DDA is time consuming.
