DIFFERENCE BETWEEN DDA AND BRESENHAM LINE ALGORITHM PDF

I am assuming you are talking about the two line drawing algorithms. The simplest answer is that Digital Differential Analyzer(DDA) involves. In the following three algorithms, we refer the one point of line as X0,Y0X0,Y0 and Step 2 − Calculate the difference between two end points. DDA uses float numbers and uses operators such as division and multiplication in its calculation. Bresenhams algorithm uses ints and only uses.

A line connects two points. It is a basic element in graphics. To draw a line, you need two points between which you can draw a line. Digital Differential Analyzer DDA algorithm is the simple line generation algorithm which is explained step by step here.

Bresenham in and it is much accurate and much more efficient than DDA. It scans the coordinates but instead of rounding them slgorithm it takes the incremental value in account by adding or subtracting and therefore can be used for drawing circle and curves.

Comparision DDA uses floating points where as Bresenham algorithm use fixed points. DDA round off the coordinates to nearest integer but Bresenham algorithm does not.

Diffeerence algorithm is much accurate and efficient than DDA.

Make a comparison between Bresenham and DDA line drawing algorithms

Bresenham algorithm can draw circles and curves with much more accuracy than DDA. Real Arithmetic Bresenhams algorithm uses fixed points i.

Operations DDA algorithms uses multiplication and division in its operations. Bresenhams algorithm uses only subtraction and addition in its Speed DDA algorithm is rather slowly than Bresenhams algorithm in line drawing dra it uses real arithmetic floating point operations.

Bresenhams algorithm is faster than DDA algorithm in line drawing because it performs only addition and subtraction in its calculations and uses only integer arithmetic so it runs significantly faster. Bresenhm algorithm is more accurate and efficient as than DDA algorithm.

Difference Between DDA and Bresenham Algorithm

Drawing DDA algorithm can draw circles and curves but that are not as accurate as Bresenhm algorithm. Bresenhm algorithm can draw circles and oine with much more accuracy than DDA algorithm.

Round off DDA algorithm round off the coordinates to integer that is nearest to the line. Bresenhm algorithm does not round off but takes the incremental value in its operation.

DDA algorithm is rather slowly than Bresenhams algorithm in line drawing because it uses real arithmetic floating point operations.

Bresenhm algorithm is less expensive than DDA algorithm as it uses only addition and subtraction.
