## What is the initial decision parameter of Bresenham line drawing algorithm?

## What is the initial decision parameter of Bresenham line drawing algorithm?

2.2 slope(m) = 1. According to slope Decision Parameter is calculated, which is used to make decision for selection of next pixel point in both the phases.

## What are the advantages of Bresenham 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.

**What are the steps of Bresenham’s circle drawing algorithm explain with example?**

Bresenham’s Circle Algorithm:

- Step1: Start Algorithm.
- Step2: Declare p, q, x, y, r, d variables.
- Step3: Enter the value of r.
- Step4: Calculate d = 3 – 2r.
- Step5: Initialize x=0.
- Step6: Check if the whole circle is scan converted.
- Step7: Plot eight points by using concepts of eight-way symmetry.

### What is the difference between DDA and Bresenham algorithm?

The main distinction between DDA algorithm and Bresenham line algorithm is that, the DDA algorithmic rule uses floating purpose values whereas in Bresenham, spherical off functions is used.

### What are the disadvantages of Bresenham’s algorithm?

Disadvantages of Bresenham Line Drawing Algorithm-

- Though it improves the accuracy of generated points but still the resulted line is not smooth.
- This algorithm is for the basic line drawing.
- It can not handle diminishing jaggies.

**Which algorithm is faster in DDA and Bresenham’s?**

Bresenham’s Algorithm is faster than DDA algorithm because it uses integer arithmetic. 4. DDA algorithm can draw circles and curves with less accuracy.

#### How is Bresenham better than DDA?

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. DDA algorithm is not as accurate and efficient as Bresenhm algorithm.

#### What is difference between DDA and Bresenham line drawing algorithm?

**How to draw a line using bresengham’s algorithm?**

Similar to the DDA algorithm, we need two endpoints, P and Q, to draw a line using Bresengham’s algorithm. Bresenham’s algorithm only uses integer values, integer comparisons, and additions.

## How do you calculate slope using Bresenham’s algorithm?

Using Bresenham’s algorithm, generate the coordinates of the pixels that lie on a line segment having the endpoints (2, 3) and (5, 8). Now let’s solve the same numerical using BLA Algorithm. S-1: x1=2; y1=3; x2=5; y2=8. Slope is more than 1 so we will follow the following method. S-3: Calculate d = 2*dx-dy , so d=2*3 – 5 = 1.

## Why is Bresenham’s Algorithm better than DDA?

Bresenham’s algorithm only uses integer values, integer comparisons, and additions. This makes Bresenham’s algorithm more efficient, fast, and easier to calculate than the DDA algorithm. Once we choose a pixel, we have two possible pixels to select as the next pixel.

**What is Bresenham’s method?**

It was developed by Bresenham. It is an efficient method because it involves only integer addition, subtractions, and multiplication operations. These operations can be performed very rapidly so lines can be generated quickly. In this method, next pixel selected is that one who has the least distance from true line.
