What is DDA line algorithm?
DDA stands for Digital Differential Analyzer. It is an incremental method of scan conversion of line. In this method calculation is performed at each step but by using results of previous steps.
Why do we prefer incremental line drawing algorithm over DDA line drawing algorithm?
It is easy to implement. It is fast and incremental. It executes fast but less faster than DDA Algorithm. The points generated by this algorithm are more accurate than DDA Algorithm.
Which is the line drawing algorithm Mcq?
Question 2: Which of the following is a line drawing algorithm? Explanation: All the mentioned algorithms: Line equation algorithm, the DDA algorithm and the Bressenham’s line drawing algorithm are used for line drawing in computer graphics.
What is line drawing algorithm in computer graphics?
In computer graphics, a line drawing algorithm is an algorithm for approximating a line segment on discrete graphical media, such as pixel-based displays and printers. On such media, line drawing requires an approximation (in nontrivial cases). Basic algorithms rasterize lines in one color.
Which of the following is a line drawing algorithm?
There are following algorithms used for drawing a line: DDA (Digital Differential Analyzer) Line Drawing Algorithm. Bresenham’s Line Drawing Algorithm. Mid-Point Line Drawing Algorithm.
Which is the line drawing algorithm?
What are the steps and rules of Bresenham algorithm?
Bresenham’s Line Algorithm:
- Step1: Start Algorithm.
- Step2: Declare variable x1,x2,y1,y2,d,i1,i2,dx,dy.
- Step3: Enter value of x1,y1,x2,y2
- Step4: Calculate dx = x2-x1
- Step5: Consider (x, y) as starting point and xendas maximum possible value of x.
- Step6: Generate point at (x,y)coordinates.
Which is an example of a DDA algorithm?
Example: A line has a starting point (1,7) and ending point (11,17). Apply the Digital Differential Analyzer algorithm to plot a line. Solution: We have two coordinates,
Which is the simplest algorithm for line drawing?
DDA Algorithm is the simplest line drawing algorithm. DDA Algorithm attempts to generate the points between the starting and ending coordinates. Calculate ΔX, ΔY and M from the given input.
Which is the DDA for plotting a line?
The integer parts of the x and y registers are used in plotting the line. In the case of the symmetrical DDA, we choose ε=2 -n ,where 2 n-1 ≤max (|∆x|,|∆y|)<2 π A line drawn with the symmetrical DDA is shown in fig:
What does DDA stand for in computer graphics?
DDA Algorithm DDA stands for Digital Differential Analyzer. It is an incremental method of scan conversion of line. In this method calculation is performed at each step but by using results of previous steps.
