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 …

Before discussing specific line drawing algorithms it is useful to note the general requirements for such algorithms. These requirements specify the desired characteristics of line.

• The line should appear as a straight line and it should start and end accurately.

• The line should be displayed with constant brightness …
