Question

What are the disadvantages of dda algorithm in computer graphics?

Answer 1

Answer:

• 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.
