## What is mid point line algorithm?

INTRODUCTION The Midpoint line algorithm is an incremental line plotting algorithm i.e. at each step we make incremental calculations based on preceding step to find next y value, in order to form a close approximation to a straight line between two points.

## What is parallel line algorithm in computer graphics?

A parallel algorithm to draw lines on a raster display is presented. The algorithm is a parallelization of Bresenham’s sequential raster line algorithm. The set-up cost is similar to that of the sequential algorithm and the remaining work is distributed evenly among the processors.

**How do you draw a line using Bresenham line drawing algorithm?**

Program to implement Bresenham’s Line Drawing Algorithm:

- #include
- #include
- void drawline(int x0, int y0, int x1, int y1)
- {
- int dx, dy, p, x, y;
- dx=x1-x0;
- dy=y1-y0;
- x=x0;

**Is midpoint line an algorithm?**

Given coordinate of two points A(x1, y1) and B(x2, y2) such that x1 < x2 and y1 < y2. The task to find all the intermediate points required for drawing line AB on the computer screen of pixels. Note that every pixel has integer coordinates.

### Why mid point line algorithm is better than DDA algorithm for drawing a line?

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

### Can every algorithm be parallelized?

Any algorithm can be parallelized, just by running the same code concurrently.. then it is successfully parallelized, just with zero performance improvement.

**How do you write a parallel algorithm?**

An algorithm is a sequence of steps that take inputs from the user and after some computation, produces an output. A parallel algorithm is an algorithm that can execute several instructions simultaneously on different processing devices and then combine all the individual outputs to produce the final result.

**How is the Bresenham algorithm used in computer graphics?**

Bresenham’s Line Drawing Algorithm in Computer Graphics. This algorithm was introduced by “Jack Elton Bresenham” in 1962. This algorithm helps us to perform scan conversion of a line. It is a powerful, useful, and accurate method. We use incremental integer calculations to draw a line.

#### How is the slope calculated in Bresenham’s algorithm?

The integer calculations include addition, subtraction, and multiplication. In Bresenham’s Line Drawing algorithm, we have to calculate the slope ( m) between the starting point and the ending point. As shown in the above figure let, we have initial coordinates of a line = ( xk, yk)

#### What is the algorithm for drawing a line?

Given coordinate of two points A (x1, y1) and B (x2, y2). The task to find all the intermediate points required for drawing line AB on the computer screen of pixels. Note that every pixel has integer coordinates. Below are some assumptions to keep algorithm simple. We draw line from left to right. Slope of the line is between 0 and 1.

**Which is the most efficient algorithm for scanning a line?**

Bresenham’s Line Algorithm This algorithm is used for scan converting a line. It was developed by Bresenham. It is an efficient method because it involves only integer addition, subtractions, and multiplication operations.
